Abstract
The ERS1 satellite altimetry raw data, with return waveforms sampled at 1/20 sec., have been processed for the entire geodetic mission, in order to get geoid slopes in high latitude areas, even over sea ice. From these, 5’ × 5’ grids of free-air gravity anomalies have been derived, covering both Arctic and Antarctic oceans. External validation was done in a few places especially over the Canadian Arctic where surface gravity measurements over sea ice were available.
This validation shows that a meaningful gravity field can be extracted from the data, although large differences with the surface measurements are found.
