FACILITATE THE USAGE OF REMOTE SENSING SURFACE TEMPERATURE ON SURFACE SOIL MOISTURE ESTIMATION

摘要

Soil moisture is a key hydrometeorological variable inrnthe hydrological cycle. There is a lack of research on thernthermal properties of moist soil which could be used forrnsatellite thermal infrared sensors. In this study, tworncatchments with different climate and geographicrnconditions in England and Australia are analysed tornexplore the relationships between soil moisture andrnsurface temperature. In Brue catchment, the statisticalrnperformance indices indicate a high performance withrnseasonal classification (R~2=0.900 and RMSE=0.030).rnBy applying the proposed method, soil moisture can berndetermined from satellite retrieved surface temperaturernwithout using any surface micro-meteorological andrnatmospheric measurements.
