Remote Sensing Inversion Model of Soil Moisture of Northern Tibet Region
Soil moisture is an important parameter to reflect surface soil properties and also is a hot topic in remote sensing inversion field. A simple and practical soil moisture retrieval regression model was established based on the sensitivity of MODIS band 7 data to moisture changes. The results showed that the new model worked well in soil moisture inversion in the study area, and significant correlation was found between the field observed data and inversed data of soil moisture (P<0.001). The new model is simple, practical and feasible, and can be used to monitor soil moisture in northern Tibet and other plateau regions.
