This dataset contains the Global Mean Sea Level (GMSL) generated from the Integrated Multi-Mission Ocean Altimeter Data for Climate Research (GMSL dataset). The GMSL is a 1-dimensional time series of globally averaged Sea Surface Height Anomalies (SSHA) from TOPEX/Poseidon, Jason-1, OSTM/Jason-2 and Jason-3. It starts in September 1992 to present, with a lag of up to 4 months. All biases and cross-calibrations have been applied to the data so SSHA are consistent between satellites. Data are reported as changes relative to January 1, 1993 and are 2-month averages. Glacial Isostatic Adjustment (GIA) has been applied. These data are available in ASCII format.

Data shown are latest available, given time needed to allow for processing.
