Welcome to the ESA (A)ATSR Online Dissemination Service
This service provides access to the ESA ERS-1/2 ATSR and Envisat AATSR full mission L1b dataset from the 4th reprocessing.
The ERS-1 ATSR products acquired during Phase E & F that were not part of the initial data release, have been fully integrated and made available for download via this service since mid-May 2025.
Note: For all ERS-1 ATSR data in Sentinel-like format acquired during Phase E & F (168 days repeat orbit), the "relative orbit" has been set to "000" in the data product file name. The correct relative orbit number is available in the header information of the products.
Users can freely browse and search the available products while registration is needed on the ESA Earth Online Portal for data download.
Clicking on the Collections button, the web interface shows the available datasets collection and allows data navigation and selection by tree view, filename, or on a geographical map. In order to download any product of interest, please sign in using the Login button above.
FTPS access: ERS and Envisat (A)ATSR products can also be downloaded from ftps://aatsr-ds.eo.esa.int via common FTP clients using "implicit FTP over TLS" and your own ESA EO Sign In credentials.
If you have not yet requested access to these data collections, visit the dataset description pages on the ESA Earth Online Portal.
