Research on Inverting Soil Moisture with FY-3A/MERSI Data

LI Shuang LI Guo-chun (Shenyang Agricultural University,Shenyang Liaoning 110866)  
Based on the analysis of applying remote sensing methods to measure soil moisture,using apparent thermal inertia model to invert soil moisture,the paper discussed a method of using FY-3A data inverting the soil moisture.Through an example,according the measured data,the relation model of the apparent thermal inertia and soil water content was fitted and the feasibility of this method was validated.Results showed that inverting spring soil moisture status in western area of Liaoning by the method,the accuracy was higher at 0~20 cm soil,but the precision was lower under 30 cm soil.Accordingly,finding a suitable FY-3A data real-time monitoring method of soil moisture could provide an available method for future by FY-3A data inverting soil moisture.
