卫星遥感微波地表发射率研究综述

Review on microwave land surface emissivity by satellite remote sensing

在大气参数反演、卫星资料同化及微波降雨算法等研究领域均需要全球尺度上较为精确的微波地表发射率数据的支持,而微波地表发射率目前难以精确的获取.鉴于此,本文介绍了三种主要的微波地表发射率估算方法,并从卫星遥感的角度阐述当前微波地表发射率的估算、应用现状及存在的问题,最后对微波地表发射率的研究做出展望.

For the atmospheric parameters retrieval,satellite data assimilation and microwave precipitation algorithms,there is a need for accurate microwave land surface emissivity（ MLSE） on the whole globe. In this paper, three microwave land surface emissivity estimation methods are introduced. The advantages and disadvantages for each estimation method are analyzed,in the end,the prospect and suggests for MLSE research are made.
