In this presentation, we present calibration and validation results for the Jason-3 measurement system.

Since its launch and very first measurements in February 2016, the Jason-3 mission has been providing very high-quality measurements of sea surface height, significant wave height and windspeed. Because it serves as a reference mission to all altimeter missions, for highest reliability, Jason-3 products are carefully calibrated and validated before public dissemination. Along-track as well as cross-overs analyses are performed, and long-term stability is monitored. We present results from our evaluation of the Jason-3 data, including overall system performance and stability. Our results are primarily based on the standard Geophysical Data Record products. However, we also consider alternative GPS-based orbit solutions from JPL.
