ESAs Soil Moisture and Ocean Salinity mission: From science to . . . SMOS was the first mission providing global measurements of L-band brightness temperatures resulting in soil moisture and ocean salinity data sets from space, directly responding to the lack of such measurements for hydrological and oceanographic applications (Kerr et al , 2010)
SMOS - an overview | ScienceDirect Topics SMOS (Soil Moisture and Ocean Salinity) is defined as a passive microwave satellite launched in November 2009 that collects global data on soil moisture and ocean salinity using its microwave imaging radiometer with aperture synthesis (MIRAS) sensor It provides measurements indicative of soil moisture and ocean conditions with a spatial resolution of 30 to 50 km and global coverage every
Satellite surface soil moisture from SMAP, SMOS, AMSR2 and ESA CCI: A . . . In spite of relatively acceptable skills of SMAP and SMOS-IC soil moisture products concerning R under moderate or dense VOD, small surface roughness, low heterogeneity conditions and temperate and cold climate types, advances in soil moisture products under high or even slightly low VOD, high roughness or topography complexity and
A novel calibration of global soil roughness effects for SMOS-IC soil . . . For SMOS, calibrating the NrP parameter was crucial for representing the angular effects of soil roughness on TB and enhancing SM and L-VOD retrievals (Escorihuela et al , 2007) These studies collectively highlight the importance of enhancing the surface roughness parameterization for improved SM and L-VOD retrievals
Resolution enhancement of SMOS brightness temperatures: Application to . . . This study presents the first resolution enhancement of SMOS brightness temperatures and its application to detect melt on the Antarctic and Greenland Ice Sheets Given the large amount of SMOS data to process, computation time is critical For this reason, we applied the rSIR algorithm rather than BG to the SMOS Level 1C (L1C) data
Multivariate data assimilation of GRACE, SMOS, SMAP measurements for . . . The SMOS SMAP-only assimilation (SM DA) improves the top soil moisture but degrades the groundwater storage estimates, whereas the GRACE-only assimilation (GRACE DA) improves only the groundwater component Assimilating both observations (multivariate DA) results in increased accuracy of both soil moisture and groundwater storage estimates
