Global Cross-Calibration of the Jason-1, Jason-2, and SARAL Missions
Event: 2014 Ocean Surface Topography Science Team Meeting
Session: Regional and Global CAL/VAL for Assembling a Climate Data Record
Presentation type: Type Oral
We present results from the global cross calibration and validation of the sea surface height and component measurements from the Jason1, Jason-2, and SARAL missions. Our study is based upon the best available products from each mission: GDR-E for Jason-1 (if available), GDR-D for Jason-2, and GDR-T for SARAL. With the goal of achieving a seamless record across these mission we focus on inter-satellite measurement differences at ground-track crossing locations (crossovers) to evaluate temporal and geographically correlated errors. We also consider global calibration and validation of measurements from each mission independently. Included in our study is consideration of differences between the significant wave height and wind speed measurements from each mission, given their influence on the sea state bias contrbution to the sea surface height measurements.
