| Abstract: | 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 reflect... |
