Due to a scheduled maintenance on the OTF infrastructure, access to the ERS and Envisat (A)SAR data on the Simple Online Catalogue (SO-Cat) dissemination tool will be unavailable on Wednesday 10 April 2019 from 09:30 to 13:30 CEST.

Due to a scheduled maintenance on the OTF infrastructure, access to the ERS and Envisat (A)SAR data on the Simple Online Catalogue (SO-Cat) dissemination tool will be unavailable on Wednesday 3 April 2019 from 09:00 to 13:00 CEST. 

Please be aware that the "EOLi-SA Catalogue and Ordering Service" is now dismissed and replaced by the ESA Simple Online Catalogue which was released in early January 2019.

Using a 25-year record of ESA satellite data, recent research shows that the pace at which Greenland is losing ice is getting faster.

Over two decades of observations by five radar satellites show the acceleration of ice loss of 30 glaciers in Western Palmer Land in the southwest Antarctic Peninsula.

Five satellites spanning two decades have revealed variations in the timing and pace of glacial retreat in West Antarctica. Some glaciers' thinning spreads up to three times faster than on neighbouring tributaries, and was offset by decades.

Since the launch of the first Earth-observing satellites in the 1970s, numerous missions from international space organisations have taken to the sky. Today, decades of data are helping scientists to build a better picture of changes to our planet.

Satellite readings show that atmospheric methane and carbon dioxide are continuing to increase despite global efforts to reduce emissions.
