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.

Due to a technical issue, the ERS-1 and -2 SAR products are currently unavailable via OTF.
Update: The issue has since been resolved
03 May 2017
A planned system maintenance will be affecting the availability of all Earth Observation (EO) SSO services at ESA-ESRIN.
The activity has been scheduled on Thursday 04 May 2017 from 09:00 to 12:00 CEST.
11 April 2017
ESA is pleased to announce that SAR data from the ERS-1 and the ERS-2 missions have been made available for direct download via the (A)SAR On-The-Fly (OTF) service.
With this release, users now have access to (A)SAR level 1 products from both ERS missions and from Envisat, covering Image Mode (IMS, IMP), Wide Swath (WSS) and Alternating Polarisation (APP, APS). All data are delivered as standard scenes in Envisat format.

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.
