Resumen:
The Argentine pampas is a wide plain with more than 40 million ha of lands suitable forcattle rearing and cropping. According to rainfall and soil quality patterns, the regionwas divided into five ecoregions: Mesopotamian, Rolling, Western, Flooding andSouthern (Figure 1). Last decades have shown an increase in extreme conditions(droughts and floods) and the need for improving prediction models. In this regard, itis expected that satellite-derived soil moisture could contribute significantly in thepredictive schemes. Over this area, the performance of both SMOS and AMSR-Esignatures in monitoring events of soil water surplus and deficit are being investigated.To this aim, a sensitivity analysis based on temporal trends of L1 products (emissivityand polarization ratio) of both instruments is in progress. Also the retrieved soilmoisture values of AMSR-E and SMOS are being compared using precipitation data andMODIS NDVI data as ancillary information. The final objective is to build a monitoringsystem based on current systems (AMSR-E and SMOS) and recently launched SACD/Aquarius.
