What is Envisat?
Envisat was ESA's successor to ERS. Envisat was launched in 2002 with 10 instruments aboard and at eight tons is the largest civilian Earth observation mission.
More advanced imaging radar, radar altimeter and temperature-measuring radiometer instruments extend ERS data sets. This was supplemented by new instruments including a medium-resolution spectrometer sensitive to both land features and ocean colour. Envisat also carried two atmospheric sensors monitoring trace gases.
The Envisat mission ended on 08 April 2012, following the unexpected loss of contact with the satellite. (See related news from 09 May 2012)

GOMOS Level 2 products (GOM_NL_2P - IPF v6.01) are now also available as user friendly products (UFP) in NetCDF4 format.
In addition users are informed that the full mission Envisat GOMOS Level 1 and 2 data sets (from 15/04/2002 to 08/04/2012), reprocessed with the ESA processor IPF version 6.01, have been migrated to the ESA EO centralised online dissemination service.
The Level 2 re-processing campaign of the full Envisat-SCIAMACHY mission (from 02/08/2002 up to 08/04/2012) has been completed with the instrument processor version 6.01, using as input the SCIAMACHY Level 1b version 8 dataset.

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.

Antarctica is surrounded by huge ice shelves. New research, using ice velocity data from satellites such as ESA's heritage Envisat, has revealed that there is a critical point where these shelves act as a safety band, holding back the ice that flows towards the sea. If lost, it could be the point of no return.

One of Greenland's glaciers is losing five billion tonnes of ice a year to the ocean, according to researchers. While these new findings may be disturbing, they are reinforced by a concerted effort to map changes in ice sheets with different sensors from space agencies around the world.
