Getting ready to chart sea level

Records show that, on average, global sea level rose by 3.2 mm a year between 1993 and 2018, but hidden within this average is the fact that the rate of rise has been accelerating over the last few years. Taking measurements of the height of the sea surface is essential to monitoring this worrying trend – and the Copernicus Sentinel-6 mission is on the way to being ready to do just this.

Glaciers lose nine trillion tonnes of ice in half a century

When we think of climate change, one of the first things to come to mind is melting polar ice. However, ice loss isn’t just restricted to the polar regions. According to research published today, glaciers around the world have lost well over 9000 gigatonnes (nine trillion tonnes) of ice since 1961, raising sea level by 27 mm.

Aeolus well on the way to improving forecasts

Assessing the accuracy of data being returned by completely new technology in space is a challenging task. But this is exactly what engineers and scientists have been dedicating their time to over the last months so that measurements of the world’s winds being gathered by Aeolus can be fed confidently into weather forecast models.

Preserving heritage data at ESA

Why is archiving and curating heritage satellite data so fundamentally important? How can heritage data from old satellites be used to compare with current findings?

Satellites key to addressing water scarcity

Today is World Water Day, but with millions of people in Mozambique, Malawi and Zimbabwe struggling to cope in the aftermath of Cyclone Idai, the notion of water shortages may not be at the forefront of our minds right now. Even so, floods, like we see here, lead to real problems accessing clean water. Whether the problem is inundation or water scarcity, satellites can help monitor this precious resource.

Copernicus Sentinel-1 maps floods in wake of Idai

As millions of people in Mozambique, Malawi and Zimbabwe struggle to cope with the aftermath of what could be the southern hemisphere’s worst storm, Copernicus Sentinel-1 is one of the satellite missions being used to map flooded areas to help relief efforts.

Taking gravity from strength to strength

Ten years ago, ESA launched one of its most innovative satellites. GOCE spent four years measuring a fundamental force of nature: gravity. This extraordinary mission not only yielded new insights into our gravity field, but led to some amazing discoveries about our planet, from deep below the surface to high up in the atmosphere and beyond. And, this remarkable mission continues to realise new science today.

Sentinels monitor converging ice cracks

The Copernicus Sentinel-1 radar mission shows how cracks cutting across Antarctica’s Brunt ice shelf are on course to truncate the shelf and release an iceberg about the size of Greater London – it’s just a matter of time.

Nitrogen dioxide pollution mapped

New maps that use information from the Copernicus Sentinel-5P satellite reveal nitrogen dioxide emission being released into the atmosphere in cities and towns across the globe.

Working towards AI and Earth observation

Satellites observing and measuring our planet deliver a huge amount of data that not only helps understand how our world is changing, but also benefits society by feeding into a myriad of everyday applications. Taking this to the next level, ESA is exploring how even more could be gained from these valuable data by using artificial intelligence (AI).

New observations for the new economy

We all listen to weather forecasts and know they rely on satellite data. What may not be so obvious is that many other aspects of our lives depend on robust satellite data, from growing crops to tackling the major issue of climate change. The socio-economic benefits of Earth observation are huge, and increasing. In Europe, ESA, Eumetsat and the EU work closely together, in long-term partnerships, to make sure these benefits are delivered.

Methane and ozone data products from Copernicus Sentinel-5P

The Copernicus Sentinel-5P mission has been used to produce global maps of two atmospheric gases responsible for making our world warmer: methane, which is a particularly potent greenhouse gas, and ozone, which is a greenhouse gas and a pollutant in the lower part of the atmosphere. The maps give insight into where these gases are coming from.

Copernicus Sentinel-1 reveals shared plumbing led to Agung awakening

EarthCARE mission to improve weather forecasts

Earth observation satellite data are crucial for generating accurate weather predictions. They provide a global picture of the current state of the atmosphere, which is used as the starting point for creating a forecast. But our knowledge of that current state is limited, partly because satellites have so far not been able to collect much information about clouds, which play a key role in the weather. The ESA/JAXA future mission EarthCARE will provide this information to improve our predictions about the future weather and climate.

Swarm helps pinpoint new magnetic north for smartphones

Since it was first measured in 1831, we have known that the magnetic north is constantly on the move. However, its tendency to slowly roam has stepped up a pace recently – so much so that the World Magnetic Model has had to be updated urgently with the pole’s new location, vital for navigation on smartphones, for example. ESA’s magnetic field Swarm mission has been key for this update.

Science key to taking the pulse of our planet

For some, the concept of ‘science’ may seem difficult or even boring, particularly if it was taught poorly at school. However, with all of us facing the consequences a rapidly changing world, science is fundamental to implementing adaptation and mitigation strategies. Thanks to satellites delivering critical science, we are better placed than ever before to cope with the challenges ahead.

More of Africa scarred by fires than thought

Wildfires can cause devastation and are also to blame for more than a quarter of greenhouse gases being released into the atmosphere. Satellites play a key role in mapping landscape scarred by fire – but the Copernicus Sentinel-2 mission has revealed that there are more fires than previously thought.

Slow flow for glaciers thinning in Asia

Providing water for drinking, irrigation and power, glaciers in the world’s highest mountains are a lifeline for more than a billion people. As climate change takes a grip and glaciers lose mass, one might think that, lubricated by more meltwater, they flow more quickly. However, satellite images from over the last 30 years show that it isn’t as simple as that.

Another El Niño on the horizon?

The jury is still out as to whether climate change will lead to stronger El Niño events, but while representatives from around 200 countries at the COP24 conference are working to breathe life into the 2105 Paris Agreement, there is a 75–80% chance that a fully-fledged event could be with us in the next couple of months.

Tackling drought issues for food security

This summer’s drought is a harsh reminder of how unusual weather can cause havoc for farmers – even in a rich part of the world like Western Europe. While there is a wealth of satellite data available to help predict the risk of drought, it can be daunting for a non-expert to handle. ESA’s Food Security Thematic Exploitation Platform makes this task much easier.
