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

Presentation type: Type Forum

The Jason-3 spacecraft has been collecting sea level measurements along the historical groundtrack since February 2016. In this poster, we present a summary of calibration and validation results, which indicate that the Jason-3 mission continues to provide altimetry products of high value for oceanographic applications at the mesoscale level and for climatic studies. In addition, we provide a preliminary cal/val assessment of Jason-3 products in their most recent GDR-F standard as compared to their current GDR-D standard. Specifically, we examine cycle-averaged statistics over cycles 24 to 53, as well as crossovers results. Lastly, we show that the Jason-2 data presented nominal performances until the spacecraft was decommissioned on 4 October 2019.
