East Antarctic Ice Sheet Surface Contours from Sattelite Radar Altimetry - A Demonstration

摘要

Retracking the surface return waveforms from 37 Seasat radar altimeter ground tracks across a 650,000 sq km study area in East Antarctica has resulted in 27,327 surface elevations for the area. It has been demonstrated that these satellite altimeter-derived surface elevations are internally consistent at the 1.5 m level and agree very well with the geoceiver coordinates and other surveys.
