Abstract
Small time (1 to 15 min) and space (0.5 to 1. 5 km) measurements of the mean rainfall rate have been made within 10 km from a dual-polarization radar, during several widespread or convective precipitation events. At first, the time and space characteristic scales of the gage and of the radar data are evaluated in order to find the minimum time interval Δt and spatial resolution Δx for which the mean rainfall rate values have a large enough statistical significance. Then the quantitative comparisons am made between the mean rainfall rate RG deduced from the gage data and that deduced from the radar measurements either without (RZ) or With (RD) using the differential reflectivity ZDR valuesKeywords
