Monitoring floods in the lower Bermejo river basin using multifrequency microwave signatures

Using Microwave Remote Sensing techniques represents an important contribution to forecasting skill of regional scale flooding events occurring over time scales of days to weeks. Furthermore, it could add skills to predictions of flood peak timing and magnitude, besides climatic change predictions. In this paper, the temporal trends of Polarization Ratio at some AMSR-E bands (C, X, and Ka) will be studied in order to show its potential in flood and rainfall monitoring. To this end ground truth data concerning rainfall and water level measurements in the lower Bermejo Basin in Argentina have been used, and a general correlation between variations of the Polarization Ratio and ground parameters has been found at the various AMSR-E frequencies.
