一种遥感和站点观测结合反演土壤水分的方法
A Method to Retrieve Soil Moisture Combining with Remote Sensing and Sites Observation
摘要
Abstract
It is a successful key to obtain the accurate maximum temperature difference within a day for using the apparent thermal inertia to retrieve soil moisture. According to physical significance of the apparent thermal inertia, the paper utilized MODIS data to get land surface albedo and used station observational data to obtain maximum temperature difference so as to established a soil moisture retrieval method. It had been verified in Leiji Town, the research region of"Bohai Granary"in Shandong Province. At the same time, it had been compared with traditional methods. The results showed that this method was superior to a traditional method and it could improve the retrieval accuracy of soil moisture effectively.关键词
