摘要：
近十年来,格陵兰和南极冰盖消融增速,两极地区显著变化。美国国家航空航天管理局(NASA)的冰、云和陆地高程卫星(ICESat)自2003年发射至2009年的在轨期间,用于定量分析冰盖和海冰的变化速率,并对这些变化的驱动机制进行检测与监测。ICESat在极地冰雪遥感应用等方面展示出了无可比拟的优势,对精确估算冰盖对海平面上升的年贡献、南北极海冰物质平衡量和计算全球生物总量具有重要的科学意义。冰、云和陆地高程卫星2号(ICESat-2)将在2015年发射,该卫星在ICESat的技术基础上,测高技术和精准度都有了很大的提高。本文评述了ICESat运行情况和应用优势,详尽地介绍了ICESat-2的任务目标、运行参数和技术改进,展望了其将来在极地科学的巨大应用前景。
