Abstract:In 2004 autumn,precipitation quantity in Jiangsu province is noticeably smaller than normals.Hilly counties suffer more serious drought.In order to get the spatial distribution information of drought,remote sensing data are used to monitor the drought.Using method of Apparent Thermal Inertia (ATI) index,spatial distribution map of ATI index of Jiangsu province are generated,with the NOAA/AVHRR retrieval data of land surface albedo and temperature of November 8,2004.After a precipitation process from November 9 to November 14,2004,spatial distribution map of ATI index of Jiangsu province are generated too,with the NOAA/AVHRR retrieval data of November 18,2004.Using the two maps mentioned above,drought conditions in Jisangsu Province are displayed thoroughly.
