Poseidon-4 Altimetry Level 2 High Resolution (baseline version F08) - Sentinel-6 - Reprocessed

This is a reprocessed dataset at baseline F08, which is continued by the NTC data stream from 9 Feb 2023 onwards. The Level 2 high resolution products contain the altimeter range, the sea surface height, the wind speed, significant wave height and all required geophysical corrections and related flags derived either from RAW or RMC, or the combination of both. Two measurement data files are available (standard and reduced), each with a different number of variables. The standard data file includes 1 Hz and 20 Hz measurements for the Ku- band as well as geophysical corrections at 1 Hz and some at 20 Hz. The reduced data file contains only 1 Hz measurements for the Ku- and C-bands as well as geophysical corrections at 1 Hz. Note that the HR data products only contain Ku-band measurements. These products are suitable for users seeking information on sea state and those creating downstream added value products from multiple altimeters. Particularly for those seeking the highest resolution measurements. 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).
