AVISO: Satellite derived Sea Surface Height above Geoid

AVISO: Satellite derived Sea Surface Height above Geoid

The sea surface height relative to the geoid (the mean ocean surface of the Earth if the ocean is at rest) is derived from TOPEX/Poseidon, Envisat, Jason-1, and OSTM/Jason-2 altimetry measurements. Altimetry is a technique for measuring height. Satellite altimetry measures the time taken by a radar pulse to travel from the satellite antenna to the surface and back to the satellite receiver. Combined with precise satellite location data, altimetry measurements yield sea-surface heights. This AVISO dataset was created by binning and averaging monthly values on 1 degree grids.

AVISO stands for "Archiving, Validation and Interpretation of Satellite Oceanographic data".
