GEOS-3 ALTIMETER GEOPHYSICAL DATA RECORD 1975-1978
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/geos3-agdra
These data consist of Geos-3 altimeter measurements produced by NOAA/NODC/Laboratory for Satellite Altimetry.
Description
The dataset contains 5,006,956 altimetric sea surface heights and supporting information such as sea state, wind speed, Schwiderski ocean tide height, and Cartwright solid-tide height. Corrections for altimeter bias, wet and dry troposheric delays, and electromagnetic bias are not included.
The corrections in this dataset (tides and even orbit height) are old and not very accurate. This dataset should only be used by those with an expertise in altimetry. Measurements are compressed to a rate of 1 per second using a trim mean filter.
