Validating Soil Moisture Estimation with Ers Pri Data: Operational Use in Decide, a Decision Support System for Floods
نویسندگان
چکیده
DeciDe, born as a project funded by ESA/ESRIN, is now a system for flood forecasting at the city of Florence based on the integration of heterogeneous data sources. For DeciDe a specific technique has been developed to use couples of ERS-2 PRI images from the same frame and track for comparison with corresponding moisture maps computed from rainfall fields. Couples of data sets are used to neglect, in the SAR data processing, the contributions of the observation geometry and soil roughness. The methodology and the first results of the ERS data analyses are presented, preceded by a short global description of the DeciDe system.

Soil moisture estimation from ERS/SAR data: toward an operational methodology
—Previous studies have shown the possibility of using European Remote Sensing/synthetic aperture radar (ERS/SAR) data to monitor surface soil moisture from space. The linear relationships between soil moisture and the SAR signal have been derived empirically and, thus, were a priori specific to the considered watershed. In order to overcome this limit, this study focused on two objectives. The ...

Soil moisture is a governing parameter in many complex environmental processes from the disciplines of meteorology, hydrology and agriculture. Since rainfall is partitioned into runoff and infiltration, the soil moisture content allows for direct information on further infiltration capability and expected runoff behavior. Spatial and temporal soil moisture variability are thus important factors...

Soil moisture content (SMC) is one of the most significant variables in drought assessment and climate change. Near-real time and accurate monitoring of this quantity by means of remote sensing (RS) is a useful strategy at regional scales. So far, various methods for the SMC estimation using a RS data have been developed. The use of spectral information based on a small range of electromagnetic...
