SAOCOM Europe data products
This collection provides access to the SAOCOM products acquired in the ASI Zone of Exclusivity, that correspond mainly to the European territory plus the international waters in front of North Africa and the Middle East, archived and catalogued in the ASI/CONAE dissemination system. ASI Zone of Exclusivity Platform SAOCOM 1A only (in future SAOCOM-1B will be added) Instrument L-Band SAR, 1.275 GHz Sensor mode STRIPMAP for data acquired at fixed azimuth steering (beam from S1 up to S10) TOPSAR for data acquired in ScanSAR like mode (Mode A, Mode B or Wide) Processing level L1A - SLC (single look complex, slat range), L1B - DI (detected image, ground range), L1C - GEC (geocoded on ellipsoid), L1D - GTC (geocoded on DEM) Resolution STRIPMAP: 10m TOPSAR Narrow: 30 - 50m TOPSAR WIDE: 50 - 100m Swath Width STRIPMAP: 20 - 40 km TOPSAR Narrow: 100 - 150 km TOPSAR Wide: 220 - 350 km Polarization Single polarization (HH or VV) only for STRIPMAP Double polarization (HHHV or VHVV) for both STRIPMAP and TOPSAR Quad Polarization for both STRIPMAP and TOPSAR

PROBA-V 1 km, 333 m, and 100 m products
The PROBA-V VEGETATION Raw products and Synthesis products provided coverage of all significant landmasses worldwide with, in the case of a 10-day synthesis product, a minimum effect of cloud cover, resulting from selection of cloud-free acquisitions during the 10-day period. It provided a daily coverage between Latitudes 35°N and 75°N, and between 35°S and 56°S, and a full coverage every two days at the equator. The VEGETATION instrument was pre-programmed with an indefinite repeated sequence of acquisitions. This nominal acquisition scenario allowed a continuous series of identical products to be generated, with the goal to map land cover and vegetation growth across the entire planet every two days.
