The measurements of the ice sheet topography will be made near-simultaneously (within 8-16 days) from both GPS and laser systems (and possibly also from an aircraft laser altimeter) and used to assess the error budgets of the GLAS satellite. The overall goal of the project is to determine the seasonal and interannual variation in surface elevation of the Antarctic ice sheet. This information is essential for predicting future changes in ice volume and sea-level. See the documentation provided in the dataset for more information. {"type": "Polygon", "coordinates": [[[68.55346, -71.22559], [73.20463, -71.22559], [73.20463, -69.05807], [68.55346, -69.05807], [68.55346, -71.22559]]]} 68.55346 73.20463 -71.22559 -69.05807 AMD AMD/AU ANTARCTICA Altimeters CEOS CONTINENT > ANTARCTICA > Amery Ice Shelf EARTH SCIENCE > CRYOSPHERE > GLACIERS/ICE SHEETS > GLACIER ELEVATION/ICE SHEET ELEVATION EARTH SCIENCE > CRYOSPHERE > GLACIERS/ICE SHEETS > ICE SHEETS ERS-1 > European Remote Sensing Satellite-1 ERS-2 > European Remote Sensing Satellite-2 GEOGRAPHIC REGION > POLAR GEOSCIENCE LASER ALTIMETER SYSTEMS GLAS GLAS > Geoscience Laser Altimeter System GPS GPS > Global Positioning System GPS > Global Positioning System Satellites GPS RECEIVERS ICE VOLUME ICESAT > Ice, Cloud and Land Elevation Satellite ICESAT-2 > Ice, Cloud, and land Elevation Satellite-2 Radar Altimeters SATELLITES SEA-LEVEL GET DATA documentDigital Download point for the data - excel spreadsheet HTML PROJECT HOME PAGE documentDigital Public information for ASAC project 1263 HTML VIEW RELATED INFORMATION > PUBLICATIONS documentDigital Download point for the publication - AAD Staff only HTML VIEW RELATED INFORMATION documentDigital Citation reference for this metadata record and dataset HTML Creative Commons by Attribution logo documentDigital PNG
