Sentinel-6 Michael Freilich Reprocessing Updates F08 completed and will be released on July 31, 2023

[colleen]

The PO.DAAC is pleased to announce the July 31 release of reprocessed Level 1A (L1A), Level 1B (L1B), and Level 2 (L2) altimetry data from the Sentinel-6 Michael Freilich/Jason CS radar altimeter mission. This mission aims to provide high-precision measurements of global sea-level that build upon the extensive record of observations from the previous Jason series altimetry missions. Datasets in this release were processed with the latest Sentinel-6 processing baseline (F08), which has been in use operationally for Non-Time Critical (NTC) datasets generated since February 2023.

In the aim of improving the mission long term stability, this F08 baseline provides new data derived from a Numerical Retracker. It presents some processing changes with the update of the altimeter antenna aperture used for the retracking algorithms (from 1.33° to 1.34°) and the update of the coefficient used to compute the ionosphere Total Electron Content (from 0.925 to 0.881, Dettmering and Schwatke [2022]). This reprocessing also brings corrections for missing files and anomalies affecting ....
