SENTINEL-3 MISSION PERFORMANCE CENTRE: ENSURING A HIGH-QUALITY ALTIMETRIC DATASET

摘要

Sentinel-3A is scheduled for launch in Oct. 2015, withrnSentinel-3B to follow 18 months later. Together thesernmissions are to take oceanographic remote-sensing intorna new operational realm. To achieve this a largernnumber of processing, calibration and validation tasksrnhave to be applied to their data in order to assess forrnquality, absolute bias, short-term changes and long-termrndrifts. ESA has funded the Sentinel-3 MissionrnPerformance Centre (S3MPC) to carry out thisrnevaluation on behalf of ESA and EUMETSAT. ThernS3MPC is run by a consortium led by ACRI [1] and thisrnpaper describes the work on the calibration/validationrn(cal/val) of the Surface Topography Mission (STM),rnwhich is co-ordinated by CLS and PML.
