Laboratory for Satellite Altimetry / Sea Level Rise

Products

The site provides estimates of sea level rise based on measurements from satellite radar altimeters. Plots and time series are available for TOPEX/Poseidon (T/P), Jason-1, and OSTM/Jason-2, which have monitored the same ground track since 1992, and for most of the altimeters that have operated since 1991, including ERS-2, GFO, and Envisat. Specific products include:

Global and regional sea level time series

Data files and plot of global and regional mean sea level time series for the major ocean basins and marginal seas.

Sea level rise maps

Data files and maps of the local rate of sea level change from 1992 to the present.

Sea level animations

Quicktime and RealPlayer animations of sea level variability.
