Abstract:
1. Introduction
The Jason-3 GDR is produced in standard GDR-D since the end of the commissioning phase (Sept 2016).
The decision to upgrade to standard GDR-F, took during OSTST 2018 (Açores), was confirm during Jason-3 2019 REVEX and OSTST 2019 (Chicago).
The Jason-3 GDR-F standard, following OSTST recommendations and 4P work held during past REVEX, was development with the double aim of improving the quality of the product, and to share a common standard with Sentinel-6/Jason-CS.
The Jason-3 GDR standard will upgrade to GDR-F on 2020 October, 29th , and GDR-F will become the operational baseline standard for Jason-3 OGDR and IGDR (from cycle 174 onwards) and GDR (from cycle 171 onwards)
This presentation will focus on the models evolution between GDR-D and GDR-F, the facilities and resources involved in this upgrade, the project schedule, and the Calval assesement performed to validate this new standard.
2. Science upgrade wrt GDR-D Standard
The presentation will address the exhaustive list of GDR-F evolutions, both models, auxiliary data and format.
3. Project Schedule
The presentation will detail the main phases of the project, from model choices to specifications and to operational switch and global reprocessing, giving the validation choices.
4. Facilities
The presentation will give key figures about human effort, processing facilities involved in the GDR-F development, operational switch and global reprocessing, and production performances.
5. Calval Results
The presentation will highlight the main early calval results obtained on the reference year.
