Poseidon-4 Level 3 Altimetry Low Resolution (baseline DT2024) - Sentinel-6 - Reprocessed

This is a reprocessed Level-3 (L3) dataset at DT-2024 baseline, which covers from 29 December 2021 to 31 December 2023.
The L3 LR products contain global valid 1Hz subsampled along-track sea level anomaly multi-mission intercalibrated (orbit error and long wave-length error) over water, based on LR Level 2P products.
The reference mission used for the altimeter inter-calibration processing is Topex/Poseidon between 01-01-1993 and 23-04-2002, Jason-1 between 24-04-2002 and 18-10-2008, OSTM/Jason-2 between 19-10-2008 and 25-06-2016, Jason-3 between 25-06-2016 and 09-02-2022, and Sentinel-6A from 10-02-2022.

These products are suitable for users seeking information on downstream sea level added value products.
Sentinel-6 is part of a series of Sentinel satellites, under the umbrella of the EU Copernicus programme. It is a collaborative Copernicus mission, implemented and co-funded by the European Commission, ESA, EUMETSAT and the USA, through NASA and the National Oceanic and Atmospheric Administration (NOAA).
