| Abstract: | Soil moisture is a key variable of land surface parameterization.Remote sensing provides the possibility for dynamic monitoring of soil moisture in a large area.Some relatively mature and extensively used methods and models for remote sensing monitoring of soil moisture are described here briefly,such as the thermal inertia method,the index method of crop water shortage,the departure method of vegetation index,the microwave remote-sensing method and the highly spectrographic method,and their advantages and disadvantages are also analyzed. |
