abstract: The high density Geosat/GM altimeter data south of 30 S have finally arrived. In addition, ERS-1 has completed more than 6 cycles of its 35-day repeat track. These data provide a dramatically improved view of the marine gravity field.
purpose: To provide easy access to global and regional gravity data and related models for scientific studies.

supplementalInformation: In addition to giving the Bounding Coordinates in latitude and longitude, the limits of coverage for the gridded and projected data sets are also given in units of measure of the projection. This is usually the distance from a central meridian (the x-coordinate),or base latitude (the y-coordinate), in meters or kilometersof the given projection. For this data set those boundariesare:The Western-most boundary: 0 kilometersThe Eastern-most boundary: 43367.407 kilometersThe Northern-most boundary: 0 kilometersThe Southern-most boundary: -23485.119 kilometers

evaluationMethodDescription: Vertical accuracy varies from source contributor to source contributor. However, vertical positions are usually taken from topographic maps of the area being surveyed, monumented benchmark locations, or they are determined by the use of the Global Positioning System (GPS). Accuracy may range from meters to centimeters or better.
