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.

—— 项目公开摘要 ——
本项目将采用GPS静态与动态测量规程，开展一系列冰盖地形测量工作，用于校准、验证新一代卫星地球科学激光测高系统（GLAS）的观测数据。上述冰盖地形测量将在8至16天的近乎同步窗口内，分别通过GPS、激光测高系统（或搭配机载激光测高仪）完成，并用于评估GLAS卫星的误差预算。本项目的总体目标为探明南极冰盖表面高程的季节与年际变化规律，该信息对预测冰体体积与海平面的未来变化具有关键意义。
