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 soil moisture obtained from the standard algorithms of SMOS and GCOM-W1 with soil moisture retrieved from SMOS multi-angular brightness temperature observations using a dielectric model specially developed for soil samples collected at the test site [1]. For soil moisture retrieval, full polarization brightness temperature product of the Centre Aval de Traitement des Données SMOS (CATDS) [2] was used. Standard soil moisture data was obtained from SMOS L3 SM products, provided by the CATDS, and GCOM-W1 L2 SMC products, provided by the Japan Aerospace Exploration Agency (JAXA) [3].
