What is ERS?
ESA's two European Remote Sensing (ERS) satellites, ERS-1 and –2, were launched into the same orbit in 1991 and 1995 respectively. Their payloads included a synthetic aperture imaging radar, radar altimeter and instruments to measure ocean surface temperature and wind fields.
ERS-2 added an additional sensor for atmospheric ozone monitoring. The two satellites acquired a combined data set extending over two decades.

Twenty years of radar coverage from ESA satellites have been used to measure the rapid thinning of Antarctica's Pine Island Glacier - and it's losing more ice than previously thought.
14 March 2012
An ESA-funded project to model sea ice dynamics using archived radar data from the Envisat and ERS missions has released its first validated datasets for the Arctic winters of 2004-11. Mapping sea ice displacement is key for climate research.

These images of Rome and its surroundings were acquired by ERS-1 and ERS-2 during their long service around the globe, providing valuable information to the scientific community for 20 years.
29 April 2009
Envisat and ERS-2, ESA's two veteran Earth missions, have completed a second tandem observation campaign. The technique involved flying the two satellites in precisely coordinated orbits, generating valuable new radar data for modelling Arctic terrain.
