RETRIEVING SOIL MOISTURE AT A TEST SITE ON THE YAMAL PENINSULA FROM SMOS MULTI-ANGULAR BRIGHTNESS TEMPERATURE OBSERVATIONS

摘要

This paper presents the results of a comparison of soilmoisture obtained from the standard algorithms ofSMOS and GCOM-W1 with soil moisture retrievedfrom SMOS multi-angular brightness temperatureobservations using a dielectric model speciallydeveloped for soil samples collected at the test site [1].For soil moisture retrieval, full polarization brightnesstemperature product of the Centre Aval de Traitementdes Données SMOS (CATDS) [2] was used. Standardsoil moisture data was obtained from SMOS L3 SMproducts, provided by the CATDS, and GCOM-W1 L2SMC products, provided by the Japan AerospaceExploration Agency (JAXA) [3].
