摘要: A simple model for simulating the L-band microwave emission from bare soils is developed. The calibrated on a large set of measurements obtained during three-month period over seven plots covering wide range surface roughness (representing total which can be expected agricultural fields), soil moisture, and temperature conditions. approach based parameterization an effective parameter as function characteristics: (standard deviation height correlation length) moisture. parameterizations that are developed independent incidence angle polarization valid in conditions, representative most typical fields, very smooth (rolled field after sowing) to rough surfaces (deeply plowed soil). This will enable use radiometric observations moisture retrieval areas.
