The area covered by this geoid estimate is -56 ° < lat < -21°, -75° < lon < -53° with grid spacing of 1.5' x 1.5'. The computation is based on the remove-restore technique, using the high resolution digital terrain model SRTM90m for the topographic reduction and the new EIGEN-GL04C geopotential model. The solution has been obtained in one step only over the whole area using the FFT estimation method.
Data are in meters, stored in an ASCII file, in grd format, parallelwise from N to S and from W to E.
