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.

New ERS-2 GOME Level 1 v5.1 dataset available online

20 June 2018

The post-operational full-mission reprocessing campaign of ERS-2 GOME consolidated data has been completed with an improved instrument processor version (Level-0-to-1 GDP Version 5.1). A new GOME Level 1b dataset has been generated for the 16-year mission period. The new data bring relevant quality improvements for the revised calibration approach, compensating aging and instrument degradation, and provide enhanced accessibility.

ATMOS 2018 Conference

11 June 2018

In the context of the EO Science for Society Programme Element, the European Space Agency is organising ATMOS 2018, a conference on the topical theme Atmosphere aimed at exploiting data from ESA and EO Missions for science and application development.

If you are interested in submitting a paper for the conference, please note that the deadline is 15 August 2018.
