Digital terrain model of Antarctica in ESRI Grid format, derived from ERS Radar Altimeter data.
Listed in NASA Earthdata CMR
ESRI formatted raster grid of the Antarctic continental terrain, derived from ERS radar altimeter data.
Description
The data is in a Polar Stereographic projection with true scale at 71 degrees South. The grid has 'no data' cells in latitudes south of 82 degrees South and steep areas of the continent, particularly along the coast.
ESA's two European Remote Sensing (ERS) satellites, ERS-1 and 2, were launched into the same orbit in 1991 and 1995 respectively. Their payloads included a synthetic aperture imaging radar, radar altimeter and instruments to measure ocean surface temperature and wind fields. ERS-2 added an additional sensor for atmospheric ozone monitoring.

The two satellites acquired a combined data set extending over two decades. The ERS-1 mission ended on 10 March 2000 and ERS-2 was retired on 05 September 2011.
