High Density GEOSAT/GM Altimeter Data

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.

    Supplemental Information: 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
    Purpose: To provide easy access to global and regional gravity data and related models for scientific studies.
