Review of the NASA IceBridge mission: Progress and prospects
美国NASA冰桥(IceBridge)科学计划:进展与展望

This paper gives a detailed review of IceBridge mission, including the on-board multiple sensors employed, the collected data, and the different levels of products. The on-board multiple sensors can be divided into five types: digital camera, lidar altimeter, radar, gravimeter, and auxiliary equipment. Prospects of research based on IceBridge data are described in four aspects: three-dimensional mapping of snow or ice, changes in glacier elevation and estimates of mass balance, detection of changes in sea ice thickness and distribution, and calibration and validation of satellite remote sensing observations. IceBridge will undoubtedly enhance the understanding of polar changes under global warming.
