A Novel Space-Time Adaptive Method for Rainfall Estimation by means of Weather Radar and Rain Gauges

In this paper, we show the application of a new method for merging weather radar data with point rainfall measurements from a network of rain gauges. The method, applied to a catastrophic rainfall event occurred in the Marche region in Italy, is based on the space-time adaptive computation of the coefficients of the power-law relationship with which radar reflectivity is converted into rainfall rate. Results are compared with those obtained by a standard method used for quantitative estimation of rainfall based on rain gauges and radar data.
