How to Access Data
Data Service Request (Restrained)
- Go to the ESA User Services Portal
- Register or log in to EO Sign In
- After logging in, complete and submit the form
- The request will be evaluated by ESA, which normally takes up to 2 weeks
- Upon successful evaluation, you will receive a confirmation email, which describes the amount of data that will be provided and details of how to download the data from the Dissemination Service.
ESA (A)SAR On-The-Fly (OTF) data processing and dissemination service allows end-users to gain direct access to the (A)SAR archive from the ERS-1, ERS-2 and Envisat Missions.
The data is collection based and allows data browse and download through the treeview, filename, as well as via geographical catalogue search based on area of interest and metadata. Interferometric search option is available for relevant collections. Data download is available via HTTPS, including bulk download functionality.
Envisat products can also be discovered through ESA's EO Catalogue (EO CAT), which allows users to browse and download products among the available datasets from ESA and Third Party Missions and instruments, using various criteria (Spatial, temporal).
For information on the (A)SAR On-The-Fly service please refer to the OTF FAQ page.
For further information about the EO Sign In Service you can visit TellUs.
Should you need support to access the data, please contact EOHelp.
Collection Description
The WS Mode Level 0 product consists of time-ordered AISPs collected while the instrument was is in Wide Swath Mode. The echo samples in the AISPs have been compressed to 4 bits per sample using FBAQ. This is a high-rate, wide swath (ScanSAR) mode so data is only acquired for partial orbit segments and is composed from five image swaths (SS1 to SS5). The Level 0 product is produced systematically for all data acquired within this mode.
The objective of this product is to offer Level 0 data for possible image processing on another processing site. It includes mandatory information for SAR processing.
Data Size: 400 km across track x 400 km along track.
