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

browse graphicPreview graphic
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.
