Over continental surfaces, SM validation requires a realistic estimation of surface SM in different areas within a SMOS footprint. SM variability depends on soil intrinsic and extrinsic factors. It is necessary to have a sampling strategy that integrates the relationships between hydrological variables, particularly SM, and the parameters of the landscape at different spatial scales.

Remote Sensing: Global Vision for Local Action. SMOS: The Beginning of a L-band Generation of Global Remote Sensed Soil Moisture Observations II
Ready to approach the scientific validation of SMOS land products
Improve both meteorological stations and SM network
The Environmental Units approach has proved to be a very useful tool in the estimation of SM over large reasonably “homogeneous” areas at SMOS scale
Conclusions
The stationary plots have been found to provide optimum representativity of the more extensive units in which they are found.
The aircraft campaigns have been very useful to validate this methodology
The combination of SURFEX – ISBA – L-MEB is actually the reliable spatialization tool for the site at different scales
