报告内容:极地海冰及其雪盖是全球气候系统的重要组成部分，随着气候变暖，北极海冰的范围和厚度发生显著变化，对北极和北半球天气气候产生重要影响。卫星测高是获取海盆尺度海冰厚度的最主要手段，为气候研究和季节预测等关键应用提供重要支撑。本报告主要介绍海冰和冰上积雪厚度反演的现状和前沿性问题，重点介绍现有测高算法的不确定性和改进方法，以及冰上积雪重建的国际现状和...

报告内容:全球和区域的水循环时空分布及变化特征研究中，现有能力的水平无论是模型预报还是观测方面还都相当有限。国际上现有的或规划近期发射的，针对水循环要素的地球观测卫星的测量能力还远不能满足水循环研究的需求。针对相关需求以及目前遥感监测中存在的缺陷和问题，创新性地设计和提出国际上第一颗新型自主的、多要素的综合水循环观测卫星-中法水循环观测卫星计划(Chi...
