| Abstract: | After an introduction of the development and the trend of dynamic monitoring of the soil moisture based on the NOAA-AVHRR remote sensing data,the paper gives a full and particular account of soil moisture retrieving method Based on the study of energy exchange at airsoil interface,the parameters of thermal equation are divided into 3 parts:micrometeorological parameter,soil physical parameter and soil surface temperature parameter;from which an improved method of retrieving soil surface thermal inertia from satellite data is developed Results are given at the end of this paper |
