Satellites:Sentinel-6A
Subject:ground-segment-anomaly
Impact:data-degraded
Detail:The wet tropospheric correction derived from the microwave radiometer on Sentinel-6 Michael Freilich as available on the Sentinel-6 Level-2 altimetry and microwave products shows a drift of approximately 5 mm in the last 3 months compared to modelled data from ECMWF. This means a degraded performance predominantly for NTC products where stability requirements are tighter.
