CERSAT

CERSAT is the satellite data processing and distribution center run by Ifremer at Brest, France, archiving and producing geophysical products from ocean and sea-ice missions. It maintains a continuous backscatter archive from C and Ku-band sensors since 1991 and delivers daily sea-ice concentration for both poles plus an Arctic sea-ice drift series from 1992, one of the longest continuous drift databases. CERSAT also processes ocean-wind and wave products from scatterometers, SAR, altimeters, and L-band radiometers across ERS, Sentinel-1, CFOSAT, and SMOS. Its long climate-quality records feed sea-ice nomenclature monitoring and route planning in polar waters.
