ERS SAR data available via ESA On-The-Fly service

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.

Processing and download of the generated "standard scene" Level 1 products is performed directly through the EOLI-SA user interface. A user manual and FAQ page are available to get started.

Note that the full mission archive for ERS SAR is available via OTF with the exception of data acquired during the last few months of the ERS-2 mission when the satellite was operated in a 3 days repeat orbit cycle (Phase B). Data from Phase B (10 March – 04 July 2011) will be released on OTF during Q2/2017*. Users who have already registered to receive Envisat ASAR data through OTF will automatically have access to the additional ERS SAR data.

For further information on the (A)SAR On-The-Fly service, please refer to the FAQ page or contact the EOHelp Team.
