Overview of Smos Retrievals over Land
The first dedicated Soil Moisture and Ocean Salinity mission (SMOS) has been launched by the European Space Agency on November 2, 2009. One novel aspect of this innovative spaceborne sensor is the use of the multi incidence angle observations for soil moisture retrieval [1]. The mission will deliver soil moisture products at least once every 3 day morning and evening at a 50 km spatial resoluti...
متن کاملTowards LPRM-based soil moisture retrievals with multi-angular microwave observations from SMOS
Passive microwave remote sensing by the Soil Moisture and Ocean Salinity (SMOS) satellite enables observations of surface soil moisture at global scale. This involves a retrieval process that uses a radiative transfer model to relate satellite-observed radiances to geophysical variables such as soil dielectric constant and soil moisture. The L-MEB (L-band Microwave Emission of the Biosphere) ba...
متن کاملSoil moisture retrieval from multi-incidence angle observations at L-band
Soil moisture is an important environmental variable in regulating energy fluxes and water infiltration near the soil surface. This makes it a significant parameter in meteorological and climate modelling applications. While ground measurement of soil moisture at a large spatial scale is cumbersome and time-consuming, remote sensing offers the advantage of frequent observations in time and spac...
متن کاملEmpirical sea ice thickness retrieval during the freeze-up period from SMOS high incident angle observations
Sea ice thickness information is important for sea ice modelling and ship operations. Here a method to detect the thickness of sea ice up to 50 cm during the freeze-up season based on high incidence angle observations of the Soil Moisture and Ocean Salinity (SMOS) satellite working at 1.4 GHz is suggested. By comparison of thermodynamic ice growth data with SMOS brightness temperatures, a high ...
متن کاملEffects of Topography on the L-band Emission of Soils. Analysis of Cosmos-australia Campaign
The Soil Moisture and Ocean Salinity (SMOS) mission will provide L-Band multi-angular measurements of the surface emission with a 2-D interferometric radiometer on a global basis [1]. Soil moisture will be retrieved from collected and simulated data using a minimization algorithm. The success of the process will partly depend on how accurate is the modelling of the surface radiation and the cor...
