Monitoring rain events in Chaco Xerophytic forest by SMOS and AMSR-E
SMOS SCIENCE WORKSHOP-Proceedings – The European Space Agency (ESA), 2011, pp 17-20
The objective of this work is to investigate the capability of SMOS and AMSR-E in monitoring rain events occurred in Chaco forest The particular region selected by us spans the North-East of Argentina In general, it is covered by continuous and deciduous forest, which is xerophytic, that is adapted to leave in an arid environment. At L band, both emissivity and Polarization Ratio are moderately sensitive to Soil Moisture, although with an appreciable dispersion. The forward model follows the TB trends, but with a general underestimation, which is particularly evident at H polarization and with dry soil. Related to this, the retrieved SM generally follows the ECMWF trend and the rainfall patterns, but SM is underestimated in dry conditions.
