Due to a scheduled maintenance on the OTF infrastructure, access to the ERS and Envisat (A)SAR data on the Simple Online Catalogue (SO-Cat) dissemination tool will be unavailable on Wednesday 10 April 2019 from 09:30 to 13:30 CEST.

Due to a scheduled maintenance on the OTF infrastructure, access to the ERS and Envisat (A)SAR data on the Simple Online Catalogue (SO-Cat) dissemination tool will be unavailable on Wednesday 3 April 2019 from 09:00 to 13:00 CEST. 

Please be aware that the "EOLi-SA Catalogue and Ordering Service" is now dismissed and replaced by the ESA Simple Online Catalogue which was released in early January 2019.

ESA is pleased to announce the release of several new features as part of the ESA On-The-Fly data processing and dissemination service providing data from the Envisat ASAR and ERS-1/2 SAR mission archives.

Using a 25-year record of ESA satellite data, recent research shows that the pace at which Greenland is losing ice is getting faster.

The GOME Total Column Water Vapour (TCWV) Climate product developed within the ESA GOME-Evolution project is now accessible from the ESA data archives together with the ERS-2 GOME data. The data is made available to users via direct download from the ESA Data Dissemination Service upon Fast Registration.

Due to a planned software maintenance on Tuesday 30 October 2018, the ERS and Envisat (A)SAR On The Fly (OTF) dissemination service will be unavailable from 09:00 to 12:00 CET.

Furthermore, the maintenance activities may impact the OTF data search on the same platform (ERS and Envisat) from 13:00 to 15:00 CET.

Due to unexpected technical problems, the ERS and Envisat (A)SAR data processing is temporarily unavailable on the OTF infrastructure.

Due to a scheduled maintenance, access to the OADS-OTF instance providing access to the ERS and Envisat (A)SAR data collections will be unavailable on Tuesday 11 September 2018, from 09:00 to 12:00 CEST and then again from 14:00 to 17:00 CEST.

Due to a scheduled maintenance, access to the ESAR OADS-OTF instance providing access to the ERS and Envisat (A)SAR data will be unavailable for 3 hours, on Tuesday 28 August 2018, starting from 10:00 CEST.
