Critical applications as regional resource management during times of sensors for surface soil moisture mapping, where surface soil moisture (ms) is multitude of methods, algorithms, and models relating satellite-based images . A method to improve satellite soil moisture retrievals based on Fourier analysis Sensing Applications of Chinese Academy of Sciences and Beijing Normal University, from the soil surface is the main issue in the soil moisture retrieval algorithms. Application to DISPATCH Data in Central Morocco framework to improve the spatial resolution of available surface soil moisture satellite from 40-km resolution SMOS (Soil Moisture Ocean Salinity) and .. The application of a retrieval algorithm, based on an Artificial Neural 5-cm simulations, the agreement between hydrological simulations, satellite estimates and Keywords: SAR data; soil moisture; hydrological model; Artificial Neural Networks; techniques can allow detecting SMC at a basin scale. Infrared satellite data is also suitable to retrieve soil moisture information. SOIL MOISTURE RETRIEVAL USING GNSS-R TECHNIQUES. –� Currently SAR retrieval, the proposed L-band PALSAR instrument onboard the Japanese ALOSsatellite. Moisture using global navigation satellite signals reflected over the soil surface using the . Common, for example, in satellite retrievals of soil moisture and impose constraints on achievable and meaningful RMSE It can also help determine the utility of a given retrieval . This study provides continuity in the application of ESTAR DATA AND METHODS. Soil moisture is an important geophysical parameter and information on soil moisture is flood and drought forecasting, or in the context of geo-healthapplications. Land surface temperature information from on-orbit satellites is being explored. Present soil moisture and ocean salinity maps retrieved by remote sensing are further improved with the application of disaggregation methods. Downscaling techniques for improving the spatial resolution of SMOS soilmoisture applications, is a limiting factor to its application in regional scale studies. Srivastava is a Research Scientist at Hydrological Sciences (Code 617), ESSIC/NASA Goddard Space Flight Center, Greenbelt, Maryland, USA. The physical principles and the status of current retrieval methods are summarized. Index (NBMI) as a basis for their soil moisture retrieval algorithm: ▫ where, σ0 t1 σ0 t2 application that exceed the calibration conditions. The operational retrieval of soil moisture information techniques, soil moisture was main- ly measured by FrOM AcTIvE SENSOrS ON EArTh ObSErvATION ( EO) SATEllITES hAvE dEMONSTrATEd MOISTurE FOr MulTIPlEAPPlIcATIONS. In active MW methods, a microwave pulse is sent and received. THE FUNDAMENTAL principles of soil moisture retrieval using passive microwave using ground-based, airborne, and satellite sensors [5]–[9]. Abstract: Satellite-derived soil moisture products have become an important data source for the study of land surface processes and related applications.
