How To Access Data
Project Proposal (Restrained)
- Go to the ESA User Services Portal
- Register or log in to EO Sign In
- After logging in, complete and submit the form with your proposed use of the data
- The proposal will be evaluated by ESA, which normally takes between 4 and 6 weeks
- Upon successful evaluation, you will receive a confirmation email, which describes the amount of data to be provided, and details of how to order the data.
Description
The archive and new tasking X-band SAR products are available from COSMO-Skymed (CSK) and COSMO-SkyMed Second Generation (CSG) missions in ScanSAR and Stripmap modes, right and left looking acquisition (20 to 60° incidence angle).
COSMO-SkyMed modes:
| Acquisition Mode | Single look Resolution [Az. X. Rg, SCS] (m) | Scene size [Az. X. Rg] (km) | Polarisation | Scene duration (seconds) | Number of looks | Multilook resolution (m) | Geolocation accuracy ±3 s (m) |
| [DGM, GEC, GTC] | |||||||

Following Processing Levels are available, for both CSK and CSG:
- SCS (Level 1A, Single-look Complex Slant): data in complex format, in slant range projection (the sensor's natural acquisition projection) and zero doppler projection, weighted and radiometrically equalised; the coverage corresponds to the full resolution area illuminated by the SAR instrument
- DGM (Level 1B, Detected Ground Multi-look): product obtained detecting, multi-looking and projecting the Single-look Complex Slant data onto a grid regular in ground: it contains focused data, amplitude detected, optionally despeckled by multi-looking approach, radiometrically equalised and represented in ground/azimuth projection
- GEC (Level 1C, Geocoded Ellipsoid Corrected): focused data, amplitude detected, optionally despeckled by multi-looking approach, geolocated on the reference ellipsoid and represented in a uniform preselected cartographic presentation. Any geometric correction derived by usage of terrain model isn't applied to this product by default
- GTC (Level 1D, Geocoded Terrain Corrected): focused data, fully calibrated with the usage of terrain model, amplitude detected, optionally despeckled by multi-looking approach, geolocated on a DEM and represented in a uniform preselected cartographic presentation. The image scene is located and accurately rectified onto a map projection, through the use of Ground Control Points (GCPs) and Digital Elevation Model (DEM); it differs from GEC for the use of the DEM (instead of reference ellipsoid) for the accurate conversion from slant to ground range and to approximate the real earth surface.
The list of available data can be retrieved using the CLEOS COSMO-SkyMed products catalogue. User registration is required to use the catalogue.
