Testing a Polarimetric Rainfall Algorithm and Comparison with a Dense Network of Rain Gauges
نویسندگان
چکیده
The paper presents an analysis of the performance of different radar algorithms for rainfall estimation. These are the conventional one based on radar reflectivity factor Z and three polarimetric estimators utilizing different combinations of Z, specific differential phase KDP, and differential reflectivity ZDR. A dense micronetwork of 42 gauges in central Oklahoma, USA, is used for validating the estimates of one-hour accumulations obtained from the nearby operational WSR-88D radar and Cimarron dualpolarization radar. Data set includes 13 storms with 39 hours of observations. An accuracy of point and areal radar rain measurements is assessed. Some radar calibration issues for both conventional and dualpolarization radar are addressed.

متن کاملMulticriteria design of rain gauge networks for flash flood prediction in semiarid catchments with complex terrain
[1] Despite the availability of weather radar data at high spatial (1 km) and temporal (5–15 min) resolution, ground‐based rain gauges continue to be necessary for accurate estimation of storm rainfall input to catchments during flash flood events, especially in mountainous catchments. Given economical considerations, a long‐standing problem in catchment hydrology is to establish optimal placem...
