CRYOSAT DATA QUALITY, PRODUCT EVOLUTIONS AND ACTIVITIES IN SUPPORT TO THE SENTINEL-3 TOPOGRAPHY MISSION

摘要

It is well known that conventional nadir altimetryrnacquisitions are not always suitable to monitor oceanicrnsmall-scale dynamics, coastal processes as well as icernsheet areas of rough topography. CryoSat (CS) is thernfirst SAR(in) altimeter concept to be flown on Earth andrntherefore represents a unique opportunity to processrnSAR data for which we still have poor knowledge. Afterrnbriefly presenting the CS data quality and recentrnevolutions, this paper provide a high level overview ofrnCS activities specifically aiming at supporting thernCopernicus Sentinel-3 Topography mission (S-3) withinrnthe framework of:rn1.The ground segment processing development andrnevolutionrn2.The data validation and quality controlrn3. The potential synergies for future scientific andrnoperational exploitation over ice and ocean.
