Geoid height of the Earth at 10 arc-minute resolution
The grid is global with node spacing of 10 arc-minutes (grid-node registered) and stored in netCDF with CF-compliant metadata. The geoid height is derived from the EIGEN-6C4 spherical harmonic model of the Earth’s gravity field with respect to the WGS84 ellipsoid.
The horizontal datum is WGS84.
There are 1081 x 2161 grid points in total. Coordinates are longitude and latitude (geodetic).
