ESA Observing the Earth

Mediterranean Sea hit by marine heatwave

Many parts of Europe saw record-breaking temperatures over the summer, but it wasn’t just the continental mainland that was affected: the Mediterranean Sea also suffered a major marine heatwave. An ESA-funded project, CAREHeat, detected one of the most intense Mediterranean marine heatwaves observed during the satellite era – with sea surface temperatures reaching 5°C higher than average.

Zooming in on drought from space

We are all aware that the summer of 2022 has been one of the hottest on record, causing drought and raging wildfires in many parts of Europe. Satellite data have been used to report the baking temperatures of the land surface and map fires, but the Copernicus Sentinel-1 radar mission has also been used to zoom in and provide very high-resolution measurements of the actual moisture content of the surface soils. Maps of northern Italy, for example, show how dry this summer has been compared to two years ago.

How do satellites monitor the ozone layer?

The ozone layer in our upper atmosphere protects Earth from the harmful effects of ultraviolet radiation. The use of human-produced chemicals in our atmosphere used for many years depleted Earth’s ozone layer. However, the reduction in the consumption of ozone-depleting substances driven by the Montreal Protocol – an international treaty designed to protect the ozone layer – has allowed for the ozone hole to slowly recover. This global agreement demonstrates the power of international commitment and immediate global action in protecting our environment.

ESA has been involved in monitoring the ozone for over two decades. Today, 16 September, marks the International Day for the Preservation of the Ozone Layer and we take a closer look at how satellite instruments carefully monitor the ozone layer over the South Pole.

Earth from Space: UK heatwave

This summer, heatwaves struck Europe, North Africa, the US and Asia with temperatures reaching over 40°C in places – breaking many long-standing records. Images from the Copernicus Sentinel-3 mission show the scale of Britain’s heatwave as it baked in extreme temperatures in August.

Taking the dazzle out of CryoSat yields a first

Since it was launched more than 12 years ago, ESA’s CryoSat ice mission has dazzled by way of its sheer technological and scientific excellence. This superb Earth Explorer satellite has returned a wealth of information that has transformed our understanding of Earth’s ice and how it is responding to climate change. In some circumstances, however, being dazzled isn’t a good thing, particularly when it comes to measuring the height of sea ice from space during the summer.

A paper published in Nature describes how scientists have now found an ingenious way of removing the pesky problem of dazzle from surface meltwater to yield the first ever continuous, year-round, altimetry measurements of sea-ice thickness in the Arctic Ocean.

Mission ends for Copernicus Sentinel-1B satellite

On 23 December 2021, Copernicus Sentinel-1B experienced an anomaly related to the instrument electronics power supply provided by the satellite platform, leaving it unable to deliver radar data. Since then spacecraft operators and engineers have been working tirelessly to rectify the issue. Unfortunately, despite all concerted efforts, ESA and the European Commission announce that it is the end of the mission for Sentinel-1B. Copernicus Sentinel-1A remains fully operational and plans are in force to launch Sentinel-1C as soon as possible.

Utah’s Great Salt Lake is disappearing

Utah’s Great Salt Lake dropped to its lowest recorded water level last month as a megadrought persists across the US southwest, forcing the fast-growing city to curb its water use. From space, satellite images show how water levels have fallen from 1985 to 2022 – exposing large expanses of lakebed.

Operation centres in tune for upcoming weather satellite

In just a few months’ time Europe’s first Meteosat Third Generation satellite will soar into the skies on an Ariane 5 rocket from French Guiana. From geostationary orbit, this new satellite, carrying two new highly sensitive instruments, will take weather forecasting to the next level. Taking a significant step towards launch, the satellite operations teams at two different centres have completed an all-important suite of tests ensuring that their procedures are fully compatible with the satellite.

EarthCARE taking wing

Tap into Europe in motion

Any movement beneath our feet – from barely perceptible subsidence to the sudden appearance of a sinkhole or a crashing landslide – spells big trouble. Even relatively modest subsidence can weaken buildings and infrastructure and lead to issues such as flooding, and at worst the abrupt disappearance of sections of land brings immediate threat to life. Monitoring and predicting our shifting land is clearly essential for adopting mitigating strategies.

And now, thanks to Europe’s environmental Copernicus programme and the Sentinel-1 radar satellite mission, the first Europe-wide subsidence and soil movement analysis service is available to the public.

EarthCARE takes a big stretch

ESA’s upcoming EarthCARE satellite mission has just taken a big stretch. Engineers have gently unfolded this new satellite’s huge five-panel solar wing to test that it will deploy correctly once it is in space. The solar wing is a critical part of the satellite, providing the energy for EarthCARE to do its job: to quantify the role that clouds and aerosols play in heating and cooling Earth’s atmosphere.

TRUTHS shines

Satellites are essential for delivering key data to understand and monitor how the climate crisis is impacting our world, but, in turn, decision-makers need to be confident in the data they use for mitigation strategies and policymaking. TRUTHS, a new ESA mission, will do just this – and, now having passed an important milestone, it is one step closer to becoming a reality.

Feeling the heat from space

With searing temperatures and a string of record highs being smashed across western Europe, the current heatwave is all too apparent. Extreme heat warnings have been issued in several countries including France, Spain and Portugal, and deadly wildfires have forced thousands to flee their homes. The satellite images here are an example of how the crisis is being viewed by satellites orbiting Earth.

City heat extremes

With air temperatures in excess of 10°C above the average for the time of year in parts of Europe, the United States and Asia, June 2022 has gone down as a record breaker. The fear is that these extreme early-season heatwaves are a taste of what could soon be the norm as climate change continues to take hold. For those in cities, the heat dissipates slower creating ‘urban heat islands’, which make everyday life even more of a struggle.

An instrument, carried on the International Space Station, has captured the recent land-surface temperature extremes for some European cities, including Milan, Paris and Prague.

Charting sea level from space

Satellite images of our planet have become essential to our survival, offering a new outlook of our world. With rising seas being one of the biggest threats to society, satellite altimeter missions such as Copernicus Sentinel-6 are essential in monitoring global and regional changes in sea level.

Unbeknown to many, the island of Crete, Greece, plays an important role in the Copernicus satellite altimetry constellation and on an international stage. Satellite altimetry data have to be continuously monitored at the ESA’s Permanent Facility for Altimetry Calibration where different techniques have pioneered the use of transponders to provide the best measurements to validate satellite altimeters in space soon after launch.

This documentary explains how measurements are taken from the top of the White Mountains to make sure users get the best data on sea height from satellite altimetry.

It features interviews with Craig Donlon, Head of ESA’s Earth Surfaces and Interior Earth and Mission Science Division and Stelios Mertikas, Director of Laboratory of Geodesy & Geomatics Engineering at the Technical University of Crete.

Living Planet concludes with record numbers

With more than 5000 participants, 240 science sessions and over 1300 oral presentations, ESA’s Living Planet Symposium comes to a close with record-breaking numbers. Held on 23-27 May at the World Conference Center in the German city of Bonn, the symposium brought together world-class scientists, business leaders, representatives from space agencies and international organisations and industry from around the world. Throughout the week, they showcased the latest advances in Earth observation and highlighted the essential role of Earth observation for decision making regarding the ongoing climate crisis. As the week draws to a close, we look back at some of the highlights of the week.

Boosting commercial Earth observation

One of the objectives of the Living Planet Symposium, taking place this week in Bonn, is to foster interaction between the institutional and commercial sectors to boost the Earth observation space economy. This is being achieved by highlighting existing partnerships, expanding the number of data users and facilitating access to private funds for companies.

Oceans and Climate

Earth’s oceans are huge heat stores, soaking up 93% of the excess heat from human activity over the past 70 years. Ocean currents redistribute heat around the planet, from the Equator to the poles. Where this ocean heat goes influences weather patterns and regional climate. As well as absorbing heat, oceans are a natural carbon sink, absorbing a quarter of carbon dioxide emissions from human activity. This has led to the acidification of ocean water, threating marine life.
The amount of heat and carbon dioxide absorbed depends on a number of ocean variables, all of which can be measured from space.

Taking climate monitoring into the future with quantum

Over the last decades, satellites measuring the many aspects of Earth have certainly demonstrated their worth with the information they yield to understand and monitor our environment and, importantly, to provide undeniable evidence of climate change for policymaking. While Europe is currently firmly placed as a world leader in Earth observation, it’s critical to stay ahead of the game by examining how even more sophisticated space technologies can be developed to return even more precise information in the future. Today, at ESA’s Living Planet Symposium, being held in Bonn, scientists dug deep into the potential of spaceborne quantum gravity sensors to do just this.

Water cycle

Imagine the world without water: as cold and lifeless as the planet Mars. Earth is unique in our solar system in being able to sustain liquid water on its surface. Water is essential for life and for Earth’s climate, helping transport heat around the planet, but it is difficult to track through the whole water cycle. The global view offered by satellites helps. ESA’s Climate Change Initiative is looking at a range of climate variables linked to the water cycle.

Putting the future in FutureEO

With scientific excellence at the very heart of ESA’s FutureEO programme, participants at this week’s Living Planet Symposium have been making it clear that new research missions to advance Earth science must continue to be realised in the future.

What can satellites reveal about climate tipping points?

The effects of our warming climate are seen across a multitude of measures, usually as incremental changes: more frequent extreme weather, heatwaves, droughts and wildfires. The cumulative impact of these changes, however, can cause fundamental parts of the Earth system to change more quickly and drastically. These ‘tipping points’ are thresholds where a tiny change pushes the system into an entirely new state.

This week, at ESA’s Living Planet Symposium, scientists came together to discuss the latest research evidence for climate tipping points and identify the opportunities and challenges of using remote sensing data to understand them.

Historic Greenland ice sheet rainfall unravelled

For the first time ever recorded, in the late summer of 2021, rain fell on the high central region of the Greenland ice sheet. This extraordinary event was followed by the surface snow and ice melting rapidly. Researchers now understand exactly what went on in those fateful summer days and what we can learn from it.

Users will be able to access greenhouse gas measurements from sites all around the world.

Revealing coastline dynamics of the Danube Delta

Hundreds of satellite images spanning 30 years have been compiled to show the evolution of the Danube Delta – the second largest river delta in Europe. These findings were presented today at ESA’s Living Planet Symposium taking place this week in Bonn, Germany.

Africa in the spotlight at Living Planet Symposium

We live in uncertain times. The detrimental impacts of climate change are being felt around the world and threatening our future, we are emerging from the global COVID pandemic that halted life as we know it for more than two years, and now the Ukraine crisis is not only a tragedy for those directly affected but its rippling effects are jeopardising energy and food security far and wide. Some nations are able to weather these storms better than others, but a number of countries in Africa, for example, are already on the back foot, particularly when it comes to food security.

Today, at ESA’s Living Planet Symposium, much of the focus was on furthering the uptake of Earth observation and advancing the digital transformation in Africa to address societal challenges.

It’s a kind of MAGIC

With well over 4000 scientists, academics, space industry personnel, institutional stakeholders, data users, students and citizens all gathered at the Living Planet Symposium, this world-renowned Earth observation event is already proving to be a bit like magic, especially after the gruelling two-year COVID pandemic. However, there’s also another kind of magic in the air creating a buzz – no, not the band Queen singing their hit single, but a potential new satellite mission called MAGIC that would shed new light on where Earth’s water is stored and how it moves from place to place.

Accelerators gear up at ESA’s Living Planet Symposium

Global climate change is the single most challenging issue faced by humanity – affecting every region, continent and ocean on Earth. It fuels a range of other top-level challenges such as food security, migration, biodiversity loss, risks to human health and economic losses.

This week, at ESA’s Living Planet Symposium taking place in Bonn, high-level ESA representatives, along with a mix of academia and policy experts, came together to discuss ESA’s ‘Space for a Green Future Accelerator’ – a major ESA initiative aiming to accelerate the use of space in Europe.

Full steam ahead for carbon dioxide monitoring mission

The Copernicus Anthropogenic Carbon Dioxide Monitoring mission has taken another step forward as ESA authorises the mission’s prime contractor, OHB, to continue the development of the first satellite that will take it to being launch-ready and, in parallel, start production on the mission’s second satellite. Celebrated at ESA’s Living Planet Symposium in Bonn, this contract rider follows an initial contract that was signed in 2020. 

Swarm unveils magnetic waves deep down

While volcanic eruptions and earthquakes serve as immediate reminders that Earth’s insides are anything but tranquil, there are also other, more elusive, dynamic processes happening deep down below our feet. Using information from ESA’s Swarm satellite mission, scientists have discovered a completely new type of magnetic wave that sweeps across the outermost part of Earth’s outer core every seven years. This fascinating finding, presented today at ESA’s Living Planet Symposium, opens a new window into a world we can never see.

Living Planet Symposium kicks off

ESA’s Living Planet Symposium has opened with a flourish with over 4000 participants including scientists, academics, space industry representatives, institutional stakeholders, data users, students and citizens gathered to discuss the latest findings on our changing planet, as well as advances in satellite technologies, new opportunities in the commercial world, and ESA’s plans for the future.

Tracking agricultural-related deforestation

The global trade in agricultural commodities provides food, fuel and fibre to consumers around the world. Commodity production, however, is also linked with negative environmental impacts, including the loss and degradation of forested land.

Approximately 90% of global deforestation is driven by agricultural expansion – a phenomenon which has roots in the global demand for products such as palm oil, soy and beef. New research reveals how satellites can be used to map and monitor forest-cover changes and help implement effective zero deforestation commitments.

Satellites improve national reporting of greenhouse gases

With the climate crisis continuing to tighten its grip, nations around the world are making efforts to reduce emissions of climate warming gases. To track action, countries report their greenhouse gas emissions to the UNFCCC – the body responsible for driving global action to combat climate change. While accurate and consistent reporting is crucial, very few countries exploit Earth observation satellite data to check and improve their estimates. Scientists have now devised new ways of comparing national greenhouse gas inventories with independent measurements taken from space.

With extreme weather events threatening to be more frequent and more severe as the climate crisis takes grip, it’s never been more important to have fast and accurate forecasts. ESA and Eumetsat are working hard to ensure that there will be a constant stream of weather data from space for the next decades and that these data will arrive faster and be more accurate compared to what we have today. It is therefore fitting that on World Meteorological Day, ESA can be assured that the first of the next generation weather satellites, Meteosat Third Generation Imager, has passed a critical set of tests, paving the way for it to be launched in December.

Filling the GOCE data gap unearths South Pole’s geological past

It’s very difficult to know what lies beneath a blanket of kilometres-thick ice, so it is hardly surprising that scientists have long contested the shape and geology of the ancient supercontinent from which East Antarctica formed over a billion years ago. An ESA-funded study can now lay some of this conjecture to rest. Using sensors on aircraft to measure changes in the gravity and magnetic signatures of the different rocks under the ice, scientists have discovered a huge bay the size of the UK formed part of the edge of East Antarctica.

Satellites support latest IPCC climate report

Human-induced climate change is causing dangerous and widespread disruption in nature, affecting the lives of billions of people around the world, according to the latest state of the climate report by the Intergovernmental Panel on Climate Change (IPCC) published this week.

The report utilises satellite observations as crucial input, including several long-term datasets of key aspects of the climate, known as Essential Climate Variables, generated via Europe’s leading research teams working as part of ESA’s Climate Change initiative.

Envisat 20-year anniversary

Twenty years ago, on the first of March 2002, ESA launched a new satellite to monitor our planet from space: Envisat. This research mission, which carried 10 instruments, would become a beacon for the development of future Earth observation satellites. In orbit for 10 years, double its projected lifespan, this flagship mission provided science with a wealth of data on the health of our planet and climate change – a treasure trove of data that is still used today. Thanks to the Heritage Space Programme, ESA ensures these precious data are preserved and made accessible for future generations.

This report includes interviews of :

- Simonetta Cheli, Director of Earth Observation, ESA–ESRIN, Frascati, Italy in English, French & Italian

- Henri Laur, Former Envisat Mission Manager, ESA–ESRIN, Frascati, Italy in English & French
