Minimize What is ERS?
Web Content Image

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.


The ERS-1 mission ended on 10 March 2000 and ERS-2 was retired on 05 September 2011.

SCIRoCCo - Research Grants Call 2015

24 June 2015

Within the SCatterometer InstRument Competence Centre project (SCIRoCCo), a number of research grants at Master, post-graduate and PhD level are available, to carry out original research based primarily on the exploitation of ERS Scatterometer data, on the intercalibration between ESCAT (the ERS Scatterometer), ASCAT (on MetOp-A) and comparisons of models and retrievals.

ERS-2 Scatterometer L2 dataset processing with ASPS v. 10.04 completed

14 May 2015

The re-processing campaign of ERS-2 Scatterometer Level 2.0 products has been completed, adopting the latest Advanced Scatterometer Processing System (ASPS) version 10.04. Data from Cycle 10 to Cycle 165 (26 March 1996 - 07 March 2011) and from the 3 days repeat cycles at the end of the mission (07 March 2011 - 05 July 2011) is now available to the user community.
