    COSMO-SkyMed full archive and tasking

    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] Stripmap Himage 2.6 x 3 40 x 40 Single: HH, HV, VH, VV 7 3 5 25 Stripmap PingPong 9.7 x 11 30 x 30 Alternate: HH/VV, HH/HV, VV/VH 6 3 20 25 ScanSAR Wide 23 x 13.5 100 x 100 Single: HH, HV, VH, VV 15 4 - 9 30 30 ScanSAR Huge 38 x 13.5 200 x 200 Single: HH, HV, VH, VV 30 25 - 66 100 100 COSMO-Skymed Second Generation Modes: Acquisition Mode Single look Resolution [Az.

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. As per ESA policy, very high-resolution data over conflict areas cannot be provided.
