摘要
本文介绍了等效反射率、平均等效反射率的概念及计算方法,以2006年10月在崇明东滩湿地采集的地面光谱反射率数据和MOD IS地面反射率产品为基础数据,计算了试验区等效反射率和平均等效反射率,开展了平均等效反射率与MOD IS反演反射率的比较分析,对MOD IS地面反射率产品精度作了分析和评价。
This paper makes an introduction to the concepts and the computational method of equivalent reflectivity and the average equivalent reflectivity. Taking ground reflectivity data gathered on October, 2006 east Chongming beach wetland and the MODIS ground reflectivity product as the foundation data, the equivalent reflectivity and the average equivalent reflectivity of this area have been calculated. We also have made comparative analysis between the average equivalent reflectivity and the MODIS retrieval reflectivity. Finally, we make the analysis and evaluation to the MODIS ground reflectivity product precision as well.
