AVISO: Satellite derived Sea Surface Height above Geoid
Years of record
- to
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…

Global Mean Sea Level from TOPEX & Jason Altimetry
Years of record
- to
The global mean sea level timeseries is an excellent, integrative indicator of climate change, providing a record independent of common metrics like global surface air temperature. The major contributions to the observed sea level trend of 3.3 mm/year include the ocean's thermal expansion, meltwater from mountain glaciers, and discharge from the Greenland and…
