Sentinel-3 Marine Altimetry Mission

Event: 2022 Ocean Surface Topography Science Team Meeting

Session: OSTST Opening Plenary Session

Presentation type: Type Poster

Sentinel-3 is part of a series of Sentinel satellites responsible for taking care of a continuous ‘health check’ of the Earth planet under the umbrella of the Copernicus program. The Copernicus program will launch four Sentinel-3 satellites (from A to D) to achieve this goal from 2016 to 2030s. EUMETSAT’s ground segment is responsible for the processing of the Sentinel-3 altimetry data in the marine environment: open ocean, coastal zones and sea level into the sea ice leads.

Since 2016 Sentinel-3A’s SRAL, Synthetic Aperture Radar Altimeter, has been successfully contributing to the continuity of the sea level climate data record. Sentinel-3B launched in 2018 completes the currently operational mission.
Besides the Sea Level, also the Wave Height, Wind Speed are retrieved.
To further improve the quality of the datasets the processing baseline has considerably evolved during the years of the mission.
The Marine datasets besides being made available to the general public, are operationally used by the Copernicus services: CMEMS (Copernicus Marine Environment Monitoring Service) and C3S (Copernicus Climate Change Service).

This presentation will provide an overview of the latest evolutions of the Sentinel-3 SRAL/MWR processing, the relations between Sentinel-3A and -3B processing, and the strategy that EUMETSAT has adopted to provide the consistent long-term data set while continuing to evolve and improve the processing algorithms and standards. The latest reprocessing “BC 004” is the baseline for a quality analysis of the Sentinel-3 Marine Centre data in a multi-mission setting. To this goal this presentation aims at: providing multi-mission time series (Sentinel-3A, Sentinel-3B, Jason-3 and Sentinel-6) of the main climate records (sea level, significant wave height, wind speed and wet troposphere path delays) in ocean surfaces; quantifying cross-overs (mono- and multi- mission); as well as provide a 5-year global assessment of SAR mode versus Pseudo-LRM. The roadmap with the upcoming baseline "BC005" will shown with its relevant impacts for sea level measurements.
