The Faraday Rotation (FR) is a non-negligible effect at the L-band, which operation frequency of Soil Moisture and Ocean Salinity (SMOS) mission. This introduces rotation in electromagnetic field polarization when propagating through ionosphere that must be compensated. Recently, methodology was developed order to retrieve Vertical Total Electron Content (VTEC) from SMOS radiometric data with a...

A single-layer Artificial Neural Network (ANN) model was developed to predict the removal efficiency of Ni(II) ions from aqueous solution using shelled Moringa Oleifera seed (SMOS) powder. Batch experiments resulted into standardization of optimum conditions: biomass dosage (4.0 g), Ni(II) concentration (25 mg/L) volume (200 mL) at pH 6.5. A time of forty minutes was found sufficient to achieve...

With the launch of the European Space Agency’s (ESA) Soil Moisture and Ocean Salinity (SMOS) mission on 2 November 2009, there is a new opportunity for global near-surface soil moisture mapping from space [1-2]. Along with its innovative sensor design, a 2-dimensional array of L-band passive microwave radiometers distributed on a Y-shaped synthetic aperture antenna, a new generation of retrieva...

L-band (1-2 GHz) microwave radiometry is a remote sensing technique that can be used to monitor soil moisture, and is deployed in the Soil Moisture and Ocean Salinity (SMOS) Mission of the European Space Agency (ESA). Performing ground-based radiometer campaigns before launch, during the commissioning phase and during the operative SMOS mission is important for validating the satellite data and...

Remotely sensed soil moisture products derived from the Advanced SCATterometer (ASCAT) and from the Soil Moisture and Ocean Salinity (SMOS) radiometer are analyzed and compared. The comparison has been carried out within the framework of an activity aiming at validating the EUMETSAT Hydrology Satellite Application Facility (H-SAF) soil moisture products derived from ASCAT over Europe and North ...

Soil moisture is one of the most important variable that in uences the soil-vegetation-atmosphere uxes. However, due to its high temporal and spatial variability, it is dif cult to provide accurate quantitative information on soil moisture at regional and global scales. Different approaches exist, but remote sensing is the more appropriated to measure soil moisture values and its variations. It...
