COVID-19: Aeolus and weather forecasts

We are all too aware that COVID-19 is a serious threat to health, is putting huge pressure on healthcare systems and it could leave the global economy struggling for years to come. With lockdown measures in force across the globe, the pandemic is also affecting aspects of everyday life that may not be so obvious. The drop in commercial flights, for example, has led to fewer measurements for weather forecasts, but fortunately, ESA’s Aeolus satellite mission is helping to fill the gap.

Mapping Chernobyl fires from space

With an outbreak of wildfires recently threatening the closed Chernobyl nuclear power plant in the Ukraine, the Copernicus Emergency Mapping Service has been activated and the Copernicus Sentinel-2 satellite mission has imaged the fires and smoke, and mapped the resulting area of burned ground.

Air pollution remains low as Europeans stay at home

Further analyses are showing the continued low levels of nitrogen dioxide concentrations across Europe – coinciding with lockdown measures implemented to stop the spread of the coronavirus. New data from the Copernicus Sentinel-5P satellite, from the European Union Copernicus programme, show some cities seeing levels fall by 45—50% compared to the same period last year.

Satellites providing clear picture of greenhouse gases

With increasing levels of greenhouse gases causing our climate to change, it is important to understand exactly where these gases come from and how they disperse in the atmosphere. A new dataset, produced by the European Space Agency’s Climate Change Initiative, provides a detailed view of carbon dioxide and methane – two of the most important human-made gases driving global warming.

Satellites and machine learning for water management

Freshwater is vital to life – but a growing global population, economic development and the effects of climate change are putting mounting pressure on this precious finite resource. Globally, agriculture accounts for 70% of all freshwater consumed, so efficient water management is essential. An ESA project that focuses on fusing data from two different Copernicus Sentinel missions is providing estimates of evapotranspiration, which is not only key for sustainable agriculture, but also important for water resource management and for a number of the United Nations’ Sustainable Development Goals.

CryoSat still cool at 10

Today marks 10 years since a Dnepr rocket blasted off from an underground silo in the remote desert steppe of Kazakhstan, launching one of ESA’s most remarkable Earth-observing satellites into orbit. Tucked safely within the rocket fairing, CryoSat had a tough job ahead: to measure variations in the height of Earth’s ice and reveal how climate change is affecting the polar regions. Carrying novel technology, this extraordinary mission has led to a wealth of scientific discoveries that go far beyond its primary objectives to measure polar ice. And, even at 10 years old, this incredible mission continues to surpass expectations.

Unusual ozone hole opens over the Arctic

Scientists using data from the Copernicus Sentinel-5P satellite have noticed a strong reduction of ozone concentrations over the Arctic. Unusual atmospheric conditions, including freezing temperatures in the stratosphere, have led ozone levels to plummet – causing a ‘mini-hole’ in the ozone layer.

COVID-19: nitrogen dioxide over China

Recent data have shown a decline of air pollution over northern Italy coinciding with its nationwide lockdown to prevent the spread of the coronavirus (COVID-19). This new map shows the variation of nitrogen dioxide emissions over China from December to March – thanks to the Tropomi instrument on board the Copernicus Sentinel-5P satellite.

Coronavirus: nitrogen dioxide emissions drop over Italy

New data from the Copernicus Sentinel-5P satellite reveal the decline of air pollution, specifically nitrogen dioxide concentrations, over Italy. This reduction is particularly visible in northern Italy which coincides with its nationwide lockdown to prevent the spread of the coronavirus.

The animation shows the fluctuation of nitrogen dioxide concentrations across Europe from 1 January 2020 until 11 March 2020, using a 10-day moving average. These data are thanks to the Tropomi instrument on board the Copernicus Sentinel-5P satellite which maps a multitude of air pollutants around the globe.

Claus Zehner, ESA’s Copernicus Sentinel-5P mission manager, comments, “The decline in nitrogen dioxide concentrations over the Po Valley in northern Italy is particularly evident.

“Although there could be slight variations in the data due to cloud cover and changing weather, we are very confident that the reduction in concentrations that we can see, coincides with the lockdown in Italy causing less traffic and industrial activities.”

Josef Aschbacher, ESA’s Director of Earth Observation Programmes, says, “Copernicus Sentinel-5P Tropomi is the most accurate instrument today that measures air pollution from space. These measurements, globally available thanks to the free and open data policy, provide crucial information for citizens and decision makers."

The coronavirus disease (COVID-19) was recently declared a pandemic by the World Health Organisation, with more than 125 000 current cases of the disease reported globally. In Italy, the number of coronavirus cases drastically soared making it the country with the largest number of cases outside of China.

In an attempt to reduce the spread of the disease, Italy’s Prime Minister Giuseppe Conte announced a lockdown of the entire country – closing schools, restaurants, bars, museums and other venues across the country.

The Sentinel-5 Precursor – also known as Sentinel-5P – is the first Copernicus mission dedicated to monitoring our atmosphere. The satellite carries the Tropomi instrument to map a multitude of trace gases such as nitrogen dioxide, ozone, formaldehyde, sulphur dioxide, methane, carbon monoxide and aerosols – all of which affect the air we breathe and therefore our health, and our climate.

Given the growing importance and need for the continuous monitoring of air quality, the upcoming Copernicus Sentinel-4 and Sentinel-5 missions, as part of the EU’s Copernicus programme, will monitor key air quality trace gases and aerosols. These missions will provide information on air quality, stratospheric ozone and solar radiation, as well as climate monitoring.

Bolivian highland heart

For Valentine’s Day, we bring you this Copernicus Sentinel-2 image capturing a beautiful heart-shaped geographical formation in the dramatic landscape of the southern highlands of Bolivia.

The highlands are part of the Altiplano, meaning High Plateau, a region that stretches almost 1000 km from Peru to Bolivia. The landscape consists of a series of basins lying about 3500 m above sea level and is the most extensive area of high plateau on Earth, outside Tibet.

This particular area featured here is a transition between the desert in the west and the tropical forest in the east. The heart-shaped formation has been moulded by many layers of different geological formations over time. The many streams and rivers visible in this image have also contributed to the shaping of the landscape as we see it today. 

This false-colour composite image was processed by selecting spectral bands that can be used for classifying geological features – but here the image processing also highlights this lovely heart  for today’s image.

Sucre, the capital of the Chuquisaca Department, is visible at the top of the image in grey. Designated a UNESCO World Heritage Site, the city lies at an elevation of around 2800 metres above sea level. To the left of Sucre, the Maragua crater can be seen – a popular hiking destination. 

Satellites, such as Copernicus Sentinel-2, allow us to capture beautiful images such as these from space, but also  to monitor changing places on Earth. Flying 800 km above, satellites take the pulse of our planet by systematically imaging and measuring changes taking place, which is particularly important in regions that are otherwise difficult to access. This allows for informed decisions to be made to help protect our world for future generations and for all citizens that inhabit our beloved Earth.

We send all our love for Valentine’s Day from the high plateaus of Bolivia – and hope we continue our celebration of love for Earth every day of the year.

This image, which was captured on 26 January 2020, is also featured on the Earth from Space video programme.

Iceberg shattered

The Pine Island Glacier recently spawned an iceberg over 300 sq km that very quickly shattered into pieces. This almost cloud-free image, captured on 11 February by the Copernicus Sentinel-2 mission, shows the freshly broken bergs in detail.

A recent animation using 57 radar images captured by the Copernicus Sentinel-1 mission shows just how quickly the emerging cracks from the glacier grew – leading to this historic calving event.

Thanks to the combination of both optical and radar images from the Copernicus Sentinel satellite missions, growing cracks were spotted in the Pine Island Glacier last year, and since then, scientists have been keeping a close eye on how quick the cracks were growing.

The Pine Island Glacier, along with its neighbour Thwaites glacier, connect the centre of the West Antarctic Ice Sheet with the ocean, and together discharge significant quantities of ice into the ocean.

Pine Island Glacier spawns piglets

As anticipated, Pine Island Glacier, known as PIG for short, in Antarctica has just spawned a huge iceberg. At over 300 sq km, about the size of Malta, this huge berg very quickly broke into many ‘piglet’ pieces the largest of which is dubbed B-49. Thanks to images from the Copernicus Sentinel satellite missions, two large rifts in the glacier were spotted last year and scientists have been keeping a close eye on how quickly these cracks were growing. This animation uses 57 radar images captured by the Copernicus Sentinel-1 mission between February 2019 and February 2020 (the last frame is from today, 11 February 2020) and shows just how quickly the emerging cracks grew and led to this calving event.

Pine Island Glacier, along with its neighbour Thwaites Glacier, connect the centre of the West Antarctic Ice Sheet with the ocean – together discharging significant quantities of ice into the ocean. These two glaciers have been losing ice over the last 25 years. Owing to their extremely remote location, satellites play a critical role in measuring and monitoring Antarctic glaciology – revealing the timing and pace of glacial retreat in Antarctica. Since the early 1990s, the Pine Island Glacier’s ice velocity has increased dramatically to values which exceed 10 m a day. Its floating ice front, which has an average thickness of approximately 500 metres, has experienced a series of calving events over the past 30 years, some of which have abruptly changed the shape and position of the ice front.

These changes have been mapped by ESA-built satellites since the 1990s, with calving events occurring in 1992, 1995, 2001, 2007, 2011, 2013, 2015, 2017, 2018, and now 2020.

Mark Drinkwater, senior scientist and cryosphere specialist remarked, “The Copernicus twin Sentinel-1 all-weather satellites have established a porthole through which the public can watch events like this unfold in remote regions around the world. What is unsettling is that the daily data stream reveals the dramatic pace at which climate is redefining the face of Antarctica.”

Since the early 1990s, the Pine Island Glacier’s ice velocity has increased dramatically to values which exceed 10 m a day. Its floating ice front, which has an average thickness of approximately 500 metres, has experienced a series of calving events over the past 30 years, some of which have abruptly changed the shape and position of the ice front.

These changes have been mapped by ESA-built satellites since the 1990s, with calving events occurring in 1992, 1995, 2001, 2007, 2013, 2015, 2017, 2018, and now 2020.

Mark Drinkwater, senior scientist and cryosphere specialist remarked, “The Copernicus twin Sentinel-1 all-weather satellites have established a porthole through which the public can watch events like this unfold in remote regions around the world. What is unsettling is that the daily data stream reveals the dramatic pace at which climate is redefining the face of Antarctica.”

Pine Island Glacier spawns piglets

As anticipated, Pine Island Glacier, known as PIG for short, in Antarctica has just spawned a huge iceberg. At over 300 sq km, about the size of Malta, this huge berg very quickly broke into many ‘piglet’ pieces the largest of which is dubbed B-49. Thanks to images from the Copernicus Sentinel satellite missions, two large rifts in the glacier were spotted last year and scientists have been keeping a close eye on how quickly these cracks were growing. This animation uses 57 radar images captured by the Copernicus Sentinel-1 mission between February 2019 and February 2020 (the last frame is from 10 February 2020) and shows just how quickly the emerging cracks grew and led to this calving event.

Pine Island Glacier, along with its neighbour Thwaites Glacier, connect the centre of the West Antarctic Ice Sheet with the ocean – together discharging significant quantities of ice into the ocean.

Earth from Space: Flevoland

In this week's edition of the Earth from Space programme, the Copernicus Sentinel-1 mission takes us over part of the Dutch province of Flevoland – the newest province in the Netherlands and one of the largest land reclamation projects in the world.

See also Flevoland, the Netherlands to download the image. 

Flevoland, the Netherlands

The Copernicus Sentinel-1 mission takes us over part of the Dutch province of Flevoland – the newest province in the Netherlands and one of the largest land reclamation projects in the world.

With almost a third of the country lying below sea level, the Netherlands is famously known as a ‘low country,’ and has a long history of land reclamation.

One reclamation project resulted in Flevoland. After a major flood it was decided to tame the Zuiderzee, a large, shallow inlet of the North Sea, to improve flood protection and also create additional land for agricultural use.

The project entailed the creation of land known as polders. The ‘Noordoostpolder,’ or the Northeast polder is the focus of this image. Over the years, the region has developed to become a home to a modern and innovative agricultural industry. The province produces predominantly apples, cereals, potatoes and flowers – with each colourful patch in the image representing a different crop.

This image combines three radar acquisitions from the Copernicus Sentinel-1 mission taken about two months apart to show change in crop and land conditions over time. The first image from 8 May 2018 is associated with red, the second from 7 July depicts changes in green, and the third from 5 September has been linked to blue.

Along the dikes of the Ijsselmeer, west of the Noordoostpolder, lies one of the largest wind farms in the Netherlands. The strong, almost star-shaped, reflections that can be seen near the shore are around 86 wind turbines. The wind farm is said to generate approximately 1.4 billion kWh of clean renewable energy per year – comparable to the power consumption of over 400 000 households.

Images acquired with radar are interpreted by studying the intensity of the backscatter radar signal, which is related to the roughness of the ground. Cities and towns are visible in white owing to the stronger reflection of the signal. Emmeloord can be seen in the centre of the Noordoostpolder, as well as several farms that appear as bright white dots along the roads.

This image is also featured on the Earth from Space video programme.

Space key to wetland conservation

Wetlands worldwide are vanishing at an alarming rate. New maps produced by ESA’s GlobWetland Africa project show how satellite observations can be used for the effective use and management of wetlands in Africa.

Lake George, Uganda

World Wetlands Day is celebrated internationally each year on 2 February. It marks the anniversary of the signing of the Convention on Wetlands of International Importance, known as the Ramsar Convention, in Ramsar, Iran, on 2 February 1971.

World Wetlands Day raises global awareness about the vital role of wetlands for our planet, paying particular attention to wetland biodiversity.

This Copernicus Sentinel-2 image takes us over Lake George, in western Uganda. In 1988, Lake George was designated as Uganda’s first Ramsar site, given its importance as a centre for biological diversity.

This equatorial lake covers an area of around 250 sq km and has an average depth of around 2.4 metres. Lake George is fed by a complex system of rivers and streams originating from the Rwenzori mountains – supplying a system of permanent swamps surrounding the lake.

A dense fringe of wetland grass, visible in bright green, can be seen around the edges of the lake in the centre of the image.

The wetlands provide a natural living space for a number of mammals including elephants, hippopotamus and antelope. They also provide a habitat for over 150 species of birds including several rare species such as the saddle-billed stork.

Seen from above, the waters of Lake George appear green as a result of the thick concentration of blue-green algae. Metal pollution, mine seepage and agricultural runoff has caused serious pollution to the lake’s waters and are severely impacting the lake’s health.

Lake George drains through the Kazinga Channel in the image’s centre. The wide, 32km long channel connects Lake George with Lake Edward, which lies on the border between Uganda and the Democratic Republic of the Congo.

The Kazinga Channel flows through the Queen Elizabeth National Park. The almost 2000 sq km park is known for its wildlife including the African buffalo and the Nile crocodile.

The park is also famous for its volcanic features, including volcanic cones and deep craters which can be seen dotted around the image. Many contain crater lakes, including the Katwe crater lake, whose salt deposits have been mined for centuries.

Sentinel-2 is a two-satellite mission to supply the coverage and data delivery needed for Europe’s Copernicus programme. The mission’s frequent revisits over the same area and high spatial resolution allow changes in inland water bodies to be closely monitored.

CryoSat sheds new light on ice loss from Antarctica’s biggest glacier

Ice loss from Pine Island Glacier has contributed more to sea-level rise over the past four decades than any other glacier in Antarctica. However, the way this huge glacier is thinning is complex, leading to uncertainty about how it is likely to raise sea level in the future. Thanks to ESA’s CryoSat mission, scientists have now been able to shed new light on these complex patterns of ice loss.

Deforestation in Bolivia

This Copernicus Sentinel-2 image features an area in the Santa Cruz Department of Bolivia, where part of the tropical dry forest has been cleared for agricultural use.

Since the 1980s, the area has been rapidly deforested owing to a large agricultural development effort where people from the Andean high plains (the Altiplano region) have been relocated to the lowlands of Bolivia.

The relatively flat lowlands and abundant rainfall make this region suitable for farming. In fact, the local climate allows farmers to benefit from two growing seasons. The region has been transformed from dense forest into a patterned expanse of agricultural land. This deforestation method, common in this part of Bolivia, is characterised by the radial patterns that can be seen clearly in the image.

Each patterned field is approximately 20 sq km and each side is around 2.5 km long.

Small settlements can be seen in the centre of each individual field in the image, which typically contain a church, a school and a soccer field. These communities are joined by a road network depicted by the straight lines that bisect the radial fields and connect the adjacent areas.

Meandering streams and rivers can be seen flowing through the fields. The long, thin strips of land in the top right of the image are most likely cultivated soybean fields.

Rainforests worldwide are being destroyed at an alarming rate. This is of great concern as they play an important role in global climate, and are home to a wide variety of plants and animals.

Because of their unique perspective from space, Earth observation satellites are instrumental in providing comprehensive information on the full extent and rate of deforestation, which is particularly useful for monitoring remote areas.

This composite image was created by combing three separate ‘Normalised Difference Vegetation Index’ images from the Copernicus Sentinel-2 mission. The first image, from 8 April 2019, is visible in red; the second from 22 June 2019, can be seen in green; and the third from 5 September 2019 can be seen in blue. The Normalised Difference Vegetation Index is widely used in remote sensing as it gives scientists an accurate measure of healthy and status of plant growth.

Taal volcano blanketed by ash

The Philippines’ Taal volcano erupted on 12 January 2020 – spewing an ash plume approximately 15 km high and forcing large-scale evacuations in the nearby area.

This almost cloud-free image was captured today 23 January at 02:20 UTC (10:20 local time) by the Copernicus Sentinel-2 mission, and shows the island, in the centre of the image, completely covered in a thick layer of ash.  

This optical image has also been processed using the mission’s short-wave infrared band to show the ongoing activity in the crater, visible in bright red. Ash blown by strong winds can be seen in Agoncillo, visible southwest of the Taal volcano. Ash has also recorded in other areas of the Batangas province, as well as Manila and Quezon.

According to The Philippine Institute of Volcanology and Seismology bulletin published today, sulphur dioxide emissions were measured at an average of around 140 tonnes. The Taal volcano still remains on alert level four, meaning an explosive eruption is possible in the coming hours or days. The highest alert level is five which indicates an eruption is taking place.

According to the National Disaster Risk Reduction and Management Council, over 50 000 people have been affected so far. In response to the eruption, the Copernicus Emergency Mapping Service was activated. The service uses satellite observations to help civil protection authorities and, in cases of disaster, the international humanitarian community, respond to emergencies.

Japanese archipelago

The Copernicus Sentinel-3 mission takes us over the Japanese archipelago – a string of islands that extends about 3000 km into the western Pacific Ocean.

While the archipelago is made up of over 6000 islands, this image focuses on Japan's four main islands. Running from north to south, Hokkaido is visible in the top right corner, Honshu is the long island stretching in a northeast–southwest arc, Shikoku can be seen just beneath the lower part of Honshu, and Kyushu is at the bottom.

Honshu’s land mass comprises approximately four-fifths of Japan’s total area. Honshu’s main urban areas of Tokyo, Nagoya, and Osaka are clearly visible in the image. The large grey area in the east of the island, near the coast, is Tokyo, while the smaller areas depicted in grey are the areas around Nagoya and Osaka.

Honshu is also home to the country’s largest mountain, Mount Fuji. A volcano that has been dormant since it erupted in 1707, Mount Fuji is around 100 km southwest of Tokyo and its snow covered summit can be seen as a small white dot.

The Sea of Japan, also referred to as the East Sea, (visible to the west of the archipelago) separates the country from the east coast of Asia. The turquoise waters surrounding the island of Hokkaido can be seen at the top of the image, while the waters in the right of the image have a silvery hue because of sunglint – an optical effect caused by the mirror-like reflection of sunlight from the water surface back to the satellite sensor.

Sentinel-3 is a two-satellite mission to supply the coverage and data delivery needed for Europe’s Copernicus environmental monitoring programme. Each satellite’s instrument package includes an optical sensor to monitor changes in the colour of Earth’s surfaces. It can be used, for example, to monitor ocean biology and water quality.

This image, which was captured on 24 May 2019, is also featured on the Earth from Space video programme.

Flooding in southern Iran

Heavy rainfall has triggered flooding in southern Iran, particularly in the Sistan and Baluchestan, Hormozgan and Kerman provinces. The downpour has led to blocked roads and destroyed bridges, crops and houses – displacing thousands of people.

This image, captured by the Copernicus Sentinel-2 mission, shows the extent of the flooding in the Sistan and Baluchestan province on 13 January 2020. Flooded areas are visible in brown, while the flooded villages are highlighted by dotted circles. Sediment and mud, caused by the heavy rains, can be seen gushing from the Bahu Kalat River, Iran, and Dasht River, Pakistan, into Gwadar Bay.

The flooding has also affected Zahedan, as well as Konarak, Saravan, Nik Shahr, Delgan, Bazman, Chabahar, Zarābād and Khash.

In response to the flood, the Copernicus Emergency Mapping Service was activated. The service uses satellite observations to help civil protection authorities and, in cases of disaster, the international humanitarian community, respond to emergencies.

Earth from Space: Faroe Islands

This week's edition of the Earth from Space programme features a Copernicus Sentinel-2 image over the Faroe Islands – located halfway between Iceland and Norway in the North Atlantic Ocean.

See also Faroe Islands to download the image.

Faroe Islands

The Copernicus Sentinel-2 mission takes us over the Faroe Islands, located halfway between Iceland and Norway in the North Atlantic Ocean. The Faroe Islands are an archipelago made up of 18 jagged islands and are a self-governing nation under the external sovereignty of the Kingdom of Denmark.

The archipelago is around 80 km wide and has a total area of approximately 1400 sq km. The official language of the Faroe Islands is Faroese, a Nordic language which derives from the language of the Norsemen who settled the islands over 1000 years ago.

The islands have a population of around 50 000 inhabitants – as well as 70 000 sheep. Around 40% of the population reside in the capital and largest city of the Faroe Islands, Tórshavn, visible on the island of Streymoy, slightly above the centre of the image.

The islands are a popular destination for birdwatchers, particularly on the island of Mykines, the westernmost island of the Faroese Archipelago. The island provides a breeding and feeding habitat for thousands of birds, including the Atlantic Puffins.

Several inland water bodies can be seen dotted around the islands. Lake Sørvágsvatn, the largest lake of the Faroe Islands, is visible at the bottom of Vágar Island to the right of Mykines. Vágar Airport, the only airport in the Faroe Islands, can be seen left of the lake.

In this image, captured on 21 June 2018, several clouds can be seen over the Northern Isles, top right of the image. Low vegetation is visible in bright green.

The unique landscape of the Faroe Islands was shaped by volcanic activity approximately 50 to 60 million years ago. The original plateau was later restructured by the glaciers of the ice age and the landscape eroded into an archipelago characterised by steep cliffs, deep valleys and narrow fjords.

The official language of the Faroe Islands is Faroese, a Nordic language which derives from the language of the Norsemen who settled the islands over 1000 years ago.

The islands are particularly known for their dramatic landscape, grass-roofed houses and treeless moorlands. The Faroe Islands boast over 1000 km of coastline and because of their elongated shape, one can never be more than five km to the ocean from any point of the islands.

This image is also featured on the Earth from Space video programme.

Aeolus winds now in daily weather forecasts

ESA’s Aeolus satellite has been returning profiles of Earth’s winds since 3 September 2018, just after it was launched – and after months of careful testing these measurements are considered so good that the European Centre for Medium-Range Weather Forecasts is now using them in their forecasts.

Aerosol spread from Australian fires

Ferocious bushfires have been sweeping across Australia since September, fuelled by record-breaking temperatures, drought and wind. The country has always experienced fires, but this season has been horrific. A staggering 10 million hectares of land have been burned, at least 24 people have been killed and it has been reported that almost half a billion animals have perished. The fires have not only decimated the land, but they have also had a serious effect on air quality.

The Copernicus Sentinel-5 Precursor mission is dedicated to monitoring air pollution by measuring a multitude of trace gases as well as aerosols – all of which affect the air we breathe. This animation shows the immense spread of aerosols from bushfires in southeast Australia between 28 December 2018 and 8 January 2020. These plumes of particles have swept over New Zealand and crossed the South Pacific Ocean, even reaching Chile and Argentina.

The Copernicus Sentinel-5 Precursor mission is dedicated to monitoring air pollution by measuring a multitude of trace gases as well as aerosols – all of which affect the air we breathe. This animation shows the immense spread of aerosols from bushfires in southeast Australia between 28 December 2019 and 8 January 2020. These plumes of particles have swept over New Zealand and crossed the South Pacific Ocean, even reaching Chile and Argentina.

Australia: like a furnace

Ferocious bushfires have been sweeping across Australia since September, fuelled by record-breaking temperatures, drought and wind. The country has always experienced fires, but this season has been horrific. A staggering 10 million hectares of land have been burned, at least 24 people have been killed and it has been reported that almost half a billion animals have perished.

Earth from Space: Tromsø

This week's edition of the Earth from Space programme features a Copernicus Sentinel-2 image over Tromsø – the largest city in northern Norway.

Tromsø, Norway

With Christmas almost here, the red and white of this Copernicus Sentinel-2 image bring a festive feel to this week’s image featuring Tromsø – the largest city in northern Norway.

This false-colour image was processed in a way that included the near-infrared channel, which makes vegetation appear bright red. The snow over the surrounding mountains is visible in white, adding to the Christmassy feel of the image.

Most of Tromsø, lies on the island of Tromsøya, visible at the top of the image. Owing to its northerly location, the city is a popular area to experience the majestic phenomenon of the aurora borealis, or northern lights.

Tromsø is over 300 km north of the Arctic Circle. During the winter, it’s shrouded in darkness – the Sun sets in late-November and doesn’t rise again until January. The image was captured on 15 October 2019, which means it is one of the last images that Sentinel-2 could acquire before darkness descended.

During the long winter months, the Copernicus Sentinel-1 mission is used to monitor this region instead of Sentinel-2. As an advanced radar mission, Copernicus Sentinel-1 can image the surface of Earth through cloud and rain and regardless of whether it is day or night.

In September 2019, the German research icebreaker Polarstern left from Tromsø for a mammoth Arctic expedition. The Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition involves the icebreaker spending a year drifting in the Arctic sea ice.

Spearheaded by the Alfred Wegener Institute (AWI), MOSAiC is the biggest shipborne polar expedition of all time. The data gathered during the expedition will be used by scientists around the world to study the Arctic as the epicentre of global warming and gain fundamental insights that are key to better understand global climate change.

Methane leak visible from space

Data from the Copernicus Sentinel-5P satellite revealed that an explosion in a natural gas well in Ohio in February 2018 released more than 50 000 tons of methane into the atmosphere. The blowout leaked more of this potent greenhouse gas in 20 days than the majority of many European nations do in a year from their oil and gas industries.

Data from the Copernicus Sentinel-5P’s Tropomi instrument revealed that 120 tons of methane were emitted per hour due to the blowout. The findings were published in a study yesterday in the Proceedings of the National Academy of Sciences, and reveals the importance of using satellite data to detect and quantify pollutants such as methane.

The location of the explosion is marked by a black dot in the image, and shows the methane emissions before and after the blowout. The black arrow indicates the wind direction and the direction of the methane plume.

Claus Zehner, ESA’s Copernicus Sentinel-5P mission manager, comments, “These Sentinel-5P measurements show that satellites can measure the concentrations of greenhouse gases emitted by a point source. The satellite’s capabilities will be further exploited with the upcoming Copernicus Carbon Dioxide Monitoring mission.”

While carbon dioxide is more abundant in the atmosphere and therefore more commonly associated with global warming, methane is about 30 times more potent as a heat-trapping gas. It usually enters the atmosphere mainly from the fossil fuel industry, landfill sites, livestock farming, rice agriculture and wetlands – but can also be released during oil and gas extraction.

Sentinel-5P, with its state-of-the-art instrument Tropomi, can also map other pollutants such as nitrogen dioxide, carbon monoxide, sulphur dioxide and aerosols – all of which affect the air we breathe and our climate.

Shedding light in the dark: radar satellites lead the way

Spare a thought this Christmas for researchers hunkered down on their Polarstern icebreaker, adrift in the frozen Arctic Ocean. Subjected to temperatures as low as –45°C and the perpetual darkness of the polar winter, they are willing participants in MOSAiC – the world’s largest and longest polar research expedition. Despite the darkness, however, the researchers and crew remain aware of what is happening close by. How? With the help of radar imaging satellites.

CryoSat maps ice shelf on the move

It is now almost 10 years since ESA’s CryoSat was launched. Throughout its decade in orbit, this novel satellite, which carries a radar altimeter to measure changes in the height of the world’s ice, has returned a wealth of information about how ice sheets, sea ice and glaciers are responding to climate change. One of the most recent findings from this extraordinary mission shows how it can be used to map changes in the seaward edges of Antarctic ice shelves.

Earth from Space: Gotland Baltic blooms

In this week's edition of the Earth from Space programme, Copernicus Sentinel-2 takes us over the green algae blooms swirling around the Baltic Sea.

Baltic blooms

The Copernicus Sentinel-2 mission takes us over the green algae blooms swirling around the Baltic Sea.

'Algae bloom' is the term used to describe the rapid multiplying of phytoplankton – microscopic marine plants that drift on or near the surface of the sea. The chlorophyll that phytoplankton use for photosynthesis collectively tints the surrounding ocean waters, providing a way of detecting these tiny organisms from space.

In most of the Baltic Sea, there are two annual blooms – the spring bloom and the cyanobacterial (also called blue-green algae) bloom in late summer.  The Baltic Sea faces many serious challenges, including toxic pollutants, deep-water oxygen deficiencies, and toxic blooms of cyanobacteria affecting the ecosystem, aquaculture and tourism.

Cyanobacteria have qualities similar to algae and thrive on phosphorus in the water. High water temperatures and sunny, calm weather often lead to particularly large blooms that pose problems to the ecosystem.

In this image captured on 20 July 2019, the streaks, eddies and whirls of the late summer blooms, mixed by winds and currents, are clearly visible. Without in situ measurements, it is difficult to distinguish the type of algae that covers the sea as many different types of algae grow in these waters.

The highest concentrations of algal blooms are said to occur in the Central Baltic and around the island of Gotland, visible to the left in the image.

Although algal blooms are a natural and essential part of life in the sea, human activity is also said to increase the number of annual blooms. Agricultural and industrial run-off pours fertilisers into the sea, providing additional nutrients algae need to form large blooms.

The bacteria that consume the decaying plants suck oxygen out of the water, creating dead zones where fish cannot survive. Large summer blooms can contain toxic algae that are dangerous for both humans and other animals.

Satellite data can track the growth and spread of harmful algae blooms in order to alert and mitigate against damaging impacts for tourism and fishing industries.
