青藏高原地表反射率卫星反演资料的评估

EVALUATION ON SURFACE ALBEDOS DERIVED FROM SATELLITE DATA OVER THE QINGHAI-XIZANG PLATEAU AREA

该文重点介绍了ＩＳＣＣＰ资料中的地表可见光反射率资料及ＬｉＺｈａｎｑｉｎｇ等用参数化反演模式从ＥＲＢＥ宽带行星反射率得到的地表反射率资料。我们选择青藏高原及其邻近地区为目标区，结合高原野外地面观测资料对它们进行了比较和评估，分析了误差的可能原因，并提出了反演青藏高原地表反射率时应注意的问题。

The visib lesurface reflectance data from ISCCP data set and the surface albedo dataderived from ERBE broadband planetary albedo data set by Li Zhanqing,et al with a simple parameterization model were recommended in this paper.Choosing the Qinghai-Xizang Plateau and its surrounding areas as target region,comparison and evaluation weremade for them by combined with the observational data from the field experiments over the Qinghai-Xizang Plateau. We analysed the possible reasons of error and proposed the opinions for improving retrieval of the surface albedo over the Qinghai-Xizang Plateau.
