This study aims to investigate a feasible regional TEC temporal fluctuations product derived from ground-based monitoring stations Western Sub Saharan African region. To assess how the existing ionospheric monitoring capabilities in that region can satisfy related requirements, for a selected science application and for Biomass external calibration.

The forthcoming launch of SAOCOM satellites will make multitemporal L band signatures available. To take benefit from this opportunity, this study analyzes and models L band signatures of typical Argentinean crops, and proposes an algorithm able to retrieve soil moisture.

The study relied on various state-of-the-art numerical tools (RT model, assimilation OSSE and NWP forecast systems) to explore the possible impact of a Geosounder mission on the retrieval of humidity and forecast. The study showcases that some specifications are valid for such an endeavor and some needs to be refined. Future works should be directed towards a more complex information content analysis with an all sky OSSE set up and maybe a multispectral/hyperspectral perspective on the channel selection.

In this work, which was managed by GEC-Marconi Research Centre under contract to ESTEC, an investigation has been performed into the temporal variation and contemporality of SAR and optical, high resolution remote sensing data. The primary aim of the study is to investigate the combination of SAR and optical data to determine, in the application areas of the cryosphere and hydrology, the so-called 'synergistic' temporal sampling requirements, i.e.
