Global calibration and validation of the Jason-1 version E GDRs

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

We present results from the global calibration and validation of the Jason-1 Version E Geophysical Data Records (GDR-E). The goal of our presentation is to provide an understanding of the impact of changes between the recently reprocessed version E and the preceding version C data products for Jason-1. To this end, we evaluate temporal and geographically correlated differences between data from these two versions of the products. Given that Jason-1 provides the important link between the Topex/Poseidon and Jason-2/OSTM data records, we also consider the impact of the new data products on the overall climate data records from the three mission by evaluating the impact on inter-mission differences during their tandem and inter-leaving phases. We consider sea surface height and its measurement system components, as well as wind speed and significant wave height.
