The AA. used a radiation-transfer equation estimate of July surface temperatures (Ts) in China's Yongding River basin based on thermal infrared Landsat TM images from 1987 and 2005 and Landsat ETM+ images from 2000. Based upon the Ts–NDVI relationship space, they analyzed the scatterplot of Ts versus NDVI to calculate a temperature–vegetation dryness index (TVDI). They used a linear regression model between soil moisture and TVDI to estimate soil moisture to depths of 10 and 20 cm. They produced a land use and cover type map by classification of the Landsat images, and used the map to study the influence of land use and cover type changes on soil moisture : farmland converted into grassland; grassland converted into farmland; and forest converted into grassland
