30-min x 30-min Terrestrial Mean Free-Air Anomalies
The 30-min x 30-min Terrestrial Mean Free-Air Gravity Anomaly and Geoid Undulations Data Base was compiled and developed by the Ohio State University. This data base was received in March 1993. Principal gravity parameters include mean elevation, mean free-air anomaly and source id. The gravity anomaly computation uses the Geodetic Reference System 1967 (GRS 67) theoretical formula. The data are global in coverage where data are available.
