GEOSAT 44: High-Accuracy, High-Resolution Gravity
This satellite altimeter data base contains precise geoid and gravity anomaly profiles which were constructed from the average of 44 repeat cycles of Geosat. The data are contained in two files: (1) geo44asc.bin (987755 records) contains the ascending profiles which run southeast to northwest between 72S and 72N, and (2) geo44des.bin (991313 records) contains all of the descending profiles. The data parameters in addition to time and location are geoid height, gravity anomaly and uncertainty in gravity anomaly. For additional information see geosat.txt in this directory.
