GLAS Validation on the Amery Ice Shelf

Metadata record for data from ASAC Project 1263 See the link below for public details on this project.---- Public Summary from Project ----The project will involve making a series of measurements of the ice-sheet topography using GPS static and kinematic procedures so that they can be used to calibrate/validate measurements made from the new generation of satellite geoscience laser altimeter systems (GLAS). 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.
