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.

GHGSat joins ESA’s Third Party Mission Programme

GHGSat, a leader in high-resolution greenhouse gas monitoring from space, has officially joined ESA’s prestigious Third Party Mission Programme. Announced today at the Living Planet Symposium currently taking place in Bonn, data from the company’s fleet of commercial satellites will be provided, free of charge, to researchers working in the fields of Earth science and climate change. 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.

SNAP spurs Earth observation innovation with one million downloads

An open-access Earth observation analysis tool that has continued to grow in popularity in the seven years since its launch has now been projected to reach one million downloads, ESA announced today at the Living Planet Symposium.

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.

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.

New research sums up sea-level rise

Sea-level rise is arguably one of the most serious consequences of the climate crisis. While using satellite data to monitor how the height of the sea is changing provides critical evidence for decision-making, satellites are also essential to measuring the individual components, such as seawater temperature and glacier melt, that contribute to the overall rise. Confidence in the accuracy of these separate measures is key. ESA-funded research now confirms that the figures match up.

ESA hosts new office to coordinate global climate modelling push

Climate models are an important tool for scientists to understand our past climate and provide projections of future change. As such, they are in increasing demand as part of efforts to avert global warming and reduce risks associated with environmental change. To meet this demand, the World Climate Research Programme will open a new international office in the United Kingdom on 1 March 2022 that will coordinate the programme’s Climate Model Intercomparison Project.

Monitoring crop health across the Netherlands

The Copernicus Sentinel satellite missions measure and image our planet in different ways to return a wealth of complementary information so that we can understand and track how our world is changing, and how to better manage our environment and resources. Thanks to the benefits of different types of data from two particular Copernicus Sentinel missions and an ingenious new dataset tool, people working in the agriculture sector, but who are not satellite data experts, can monitor the health and development of crops, right down to each crop in individual fields.

The Copernicus Sentinel-2 mission takes us over northwest Lesotho – a small, land-locked country surrounded entirely by South Africa.

Permafrost thaw: it’s complicated

One of the many serious consequences of the climate crisis is that precious permafrost is thawing, and this is unleashing even more carbon to the atmosphere and further exacerbating climate change. However, it’s complicated. For example, sometimes permafrost can thaw rapidly and scientists are unsure why and what these abrupt thaws mean in terms of feedback loops. This makes it difficult to predict the future impact on the climate. Thanks to an ESA–NASA initiative, new research digs deep into understanding the complexities of permafrost thaw and how carbon is released over time.

In July 2017, a giant iceberg, named A-68, snapped off Antarctica’s Larsen-C ice shelf and began an epic journey across the Southern Ocean. Three and a half years later, the main part of iceberg, A-68A, drifted worryingly close to South Georgia. Concerns were that the berg would run aground in the shallow waters offshore. This would not only cause damage to the seafloor ecosystem but also make it difficult for island wildlife, such as penguins, to make their way to the sea to feed. Using measurements from satellites, scientists have charted how A-68A shrunk towards the end of its voyage, which fortunately prevented it from getting stuck. However, the downside is that it released a colossal 152 billion tonnes of freshwater close to the island, potentially having a profound effect on the island’s marine life.

Earth from Space: Kangerlussuaq Glacier

The Kangerlussuaq Glacier, one of Greenland’s largest tidewater outlet glaciers, is pictured in this false-colour image captured by the Copernicus Sentinel-1 mission. Meaning ‘large fjord’ in Greenlandic, the Kangerlussuaq Glacier flows into the head of the Kangerlussuaq Fjord, the second largest fjord in east Greenland.

Ride into space on Vega-C secured for FLEX and Altius

A contract signed with Arianespace secures the joint launch for two satellites that will further knowledge of our home planet. Scheduled to lift off on a new class of rocket, ESA’s Vega-C, from Europe’s Spaceport in mid-2025, FLEX will yield new information about the health of the world’s plants and Altius will deliver profiles of ozone and other trace gases in the upper atmosphere to support services such as weather forecasting.
