    • NOAA Laboratory for Satellite Altimetry Sea Level Rise Products: Global and regional sea level time series and trend maps for the major ocean basins and marginal seas, based on measurements from satellite radar altimeters, since 1992

    Metadata Updated: June 1, 2025

    This dataset contains global and regional mean sea level time series and trend maps calculated on a continual basis since December 1992 by Laboratory for Satellite Altimetry (LSA), Center for Satellite Applications and Research (STAR), NESDIS/NOAA. They are based on data from the series of reference missions (TOPEX/Poseidon, Jason-1 and Jason-2) that provide global mean sea level about every ten days with an uncertainty of 2-4 mm. In addition, estimates of mean sea level are also calculated from other satellite altimeter missions, including Geosat Follow-on, Envisat, ERS-1, and ERS-2.
