I want Sea Surface Height Anomalies (SSHA). Where do I get them?
There are several datasets at PO.DAAC that contain SSHA.
Reconstructed Sea Level contains SSHA on half degree grid back to 1950. Because of the reconstruction technique this dataset is several years behind the present.

TOPEX/Poseidon (1992-2005) Historical along-track swaths.
Jason-1 (2002-2012) Geodetic (2012-2013) Historical along-track swaths. The typical orbit, same as TOPEX/Poseidon, was 2002-2012 and the geodetic orbit was 2012-2013.
