Copernicus Sentinel-1 maps floods in wake of Idai

20 March 2019

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

20 March 2019

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.

Bering in dire straits

14 March 2019

The Bering Strait is a sea passage that separates Russia and Alaska. It is usually covered with sea ice at this time of year – but as this image captured by the Copernicus Sentinel-1 mission on 7 March 2019 shows, it is virtually ice-free.

Sentinels monitor converging ice cracks

14 March 2019

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

12 March 2019

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.

Proba-V 2018-2019 Antarctica data now available

07 March 2019

For the second consecutive austral summer season (see the 2018 news), Proba-V observed Antarctica and its ongoing changes: observations on the continent's land and sea ice surfaces were performed from 12 November 2018 until 18 February 2019.

EarthCARE mission to improve weather forecasts

06 March 2019

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.

Methane and ozone data products from Copernicus Sentinel-5P

04 March 2019

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

22 February 2019

When Mount Agung in Indonesia erupted in 2017, the search was on to find out why it had stirred. Thanks to information on ground deformation from the Copernicus Sentinel-1 mission, scientists now have more insight into the volcano's hidden secrets that caused it to reawaken.

Catching the world in a box

15 February 2019

The rapid evolution of Egypt's Nile Delta over the last four years, as viewed from ESA's Proba-V microsatellite. Think of it as a small token of our love for planet Earth: just a cubic metre in size, Proba-V maps land cover and vegetation growth across the entire world every two days.
