The satellite based passive (radiometer) and active (radar) microwave sensors enhanced
our ability to retrieve soil moisture at global scales. It has been almost four decades since …

Soils are at the crossroads of many existential issues that humanity is currently facing. Soils
are a finite resource that is under threat, mainly due to human pressure. There is an urgent …

The Soil Moisture and Ocean Salinity (SMOS) mission is European Space Agency (ESA's)
second Earth Explorer Opportunity mission, launched in November 2009. It is a joint …

In the near future, the SMOS (Soil Moisture and Ocean Salinity) mission will provide global
maps of surface soil moisture (SM). The SMOS baseline payload is an L-band (1.4 GHz) two …

The aim of this study is to analyze the influence of the soil moisture sampling depth in the
parameterization of soil emission in microwave radiometry at L-band. The analysis is based …

Satellite-based passive microwave remote sensing has been shown to be a valuable tool in
map** and monitoring global soil moisture. The Advanced Microwave Scanning …

In the forward model L-band microwave emission of the biosphere (L-MEB) used in the Soil
Moisture and Ocean Salinity level-2 retrieval algorithm, modeling of the roughness effects is …

The objective of the NASA Soil Moisture Active Passive (SMAP) mission is to provide global
measurements of soil moisture and freeze/thaw states. SMAP integrates L-band radar and …

Active radar backscatter (σ°) observations from the Advanced Scatterometer (ASCAT) and
passive radiometer brightness temperature (TB) observations from the Soil Moisture Ocean …

A simple reflectivity model of a bare soil at L-band is developed to account for the effects of
soil roughness at different angles and polarizations. This model was developed using a long …
