Session: Regional and Global CAL/VAL for Assembling a Climate Data Record

Presentation type: Type Oral

As Jason-3 and Sentinel-3A missions approach nearly three years of operations, the system drifts in mean sea level can be determined via the global tide gauge network with uncertainties less than 1 mm/year. Here we extend previously presented work using the combined TOPEX/Jason-1/Jason-2/Jason-3 dataset to estimate the drift in Jason-3. We also examine the drift in Sentinel-3A using comparisons with the gauges by making comparisons for each half cycle (13.5 days) using both SARM and PLRM processing. We will also demonstrate how a combined time series from Sentinel-3A and tandem phase Sentinel-3B data can be beneficial for estimating system stability during the commissioning of Sentinel-3B. Using the results from the Jason and Sentinel-3 missions, we discuss our expectations for the monitoring changes in the bias for Sentinel-6/Jason-CS missions.
