Land surface temperature is an important driving force in the exchange of water, heat, and even CO2 at the surface-atmosphere interface in the desert regions. The rapid and continuous measurements of land surface temperature are meaningful to the ecological and environmental researches. A physically based single-frequency and double-polarization algorithm for retrieving land surface temperature is...
Soil moisture is a key variable that influences the redistribution of the radiant energy and the runoff generation and percolation of water in soil. Knowledge of soil moisture temporal-spatial variations is important in a wide range of studies. This study aims to investigate the temporal-spatial variations of soil moisture using microwave polarization difference index (MPDI). The AMSR-E/Aqua Daily...
Soil moisture (SM) is a major concern in the earth science. In previous studies, in the process of retrieval of SM from remote sensing data, surface roughness effects on the retrieval of SM is obvious and a priori knowledge of surface roughness is necessary. In this paper, a simple method to retrieve SM from passive microwave data is proposed. Using the proposed method, surface roughness effects on...
