【摘要】 全球和区域降水分布的定量测量在灾害性天气的监测预报、全球水分和能量循环及气候变化研究中具有重要的应用价值。实测研究表明，空基微波遥感在全球范围降水分布的测量中是十分有效的方法。因此，全球云雨分布的空间遥感一直受到国内外有关部门的关注。我国８６３ 计划等航天技术的空间地球科学研究中把云雨遥感作为对地观测的重点之一；许多国际性大气科学实验计划中也把全球降水遥感计划列为重要科学问题加以研究。主要介绍了空基降水分布的理论模式和反演方法方面的研究进展以及面临的一些关键性问题等，最后还讨论了需要深入研究的问题。更多还原

【Abstract】 Rainfall distribution over global and regional scales plays an important role in severe weather monitoring,and in the research and application for climate change and global water cycle within the ocean land atmosphere system.Satellite borne microwave(MW) remote sensing has been proved as a powerful tool for global rainfall estimation.Therefore space borne remote sensing of rainfall estimation is one of the main project of Chinese National High Tech R & D Program for Space Technology.Also,it is one of the important problems in many international project of atmospheric scientific experiment.In this paper,we intend to review the models,retrieval algorithms,key problems in space borne remote sensing of rainfall distribution.Finally some problems which should be investigated more deeply are briefly discussed.更多还原
