Directory Title: GEOSAT 44: High-Accuracy, High-Resolution Gravity
                 Profiles (from the first 2 years of the GEOSAT
                 Exact Repeat Mission)

Summary: 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.

NOTE: GEOSAT66 data has been received from Scripps Oceanographic 
Institute, (Dr. David Sandwell).  Due to its increased size it is 
not included on this CD-ROM.  The data is, however, available from 
NGDC.
