Abstract L band microwave can penetrate the soil, and its bright temperature data contain layers of soil temperature information within the penetration depth. L band effective soil temperature and infrared soil temperature have different physical significances and values. The SHAW model was verified by using the observed data of the automatic weather station in Huailai and was driven to simulate the soil temperature and humidity profile data by using 2006~2009 meteorological observation data from Huailai experimental area. The L band effective soil temperature was computed using the soil temperature and humidity profile data in an hour interval. An analysis of the difference between infrared soil temperature and L band effective soil temperature was made tentatively. The result constitutes a basis for further exploration of the relationship between infrared soil temperature and L band effective soil temperature and also provides a theoretical support for concerted inversion of soil temperature combining infrared and passive microwave data.
