Laser Altimetry for Ice-Sheet Volume-Balance: A Use of the SOAR Facility

该奖项是为了支持一项为期三年的研究，该研究旨在对南极冰盖的高度进行精确和准确的测量，以探测冰盖表面的持续变化。发现的变化的位置和模式可以用来推断变化的原因。南极航空地球物理研究支助办公室（SOAR）设施中有适合这些测量的设备。该项目将评估质量并校准由SOAR进行的测量。测试将在飞机停放时进行，也将在飞机基地附近的地面测量地点进行。在验证和校准完成后，将启动一个有限的测量程序，以检测冰川学上感兴趣的地点的地表高程的时间变化。在该计划结束时，将建立SOAR设施准确和精确地确定表面高程的能力。然后，SOAR将对所有对精确测绘和探测南极冰盖变化感兴趣的研究人员有用。

This award is for support for a three year study to make precise and accurate measurements of the elevation of the Antarctic ice sheet in order to detect on-going changes in the surface of the ice sheet. The location and pattern of change discovered may be used to deduce the causes of the changes. Suitable equipment for these measurements are part of the Support Office for Aerogeophysical Research in Antarctica (SOAR) facility. This project will evaluate the quality and calibrate the measurements to be made by SOAR. Test will be made both while the aircraft is parked and during flights over ground-surveyed sites near the aircraft base camp. After the validation and calibration is complete, a limited measurement program to detect time changes in surface elevation of glaciologically interesting sites will be started. At the conclusion of the program the capability of the SOAR facility to accurately and precisely determine surface elevation will be established. SOAR will then be useful to all investigators who are interested in precision mapping and detection of change in the Antarctic ice sheet.
