Rainfall rate retrieval in presence of path attenuation using C-band polarimetric weather radars
Weather radar systems are very suitable tools for the monitoring of extreme rainfall events providing measurements with high spatial and temporal resolution over a wide geographical area. Nevertheless, radar rainfall retrieval at C-band is prone to several error sources, such as rain path attenuation which affects the accuracy of inversion algorithms. In this paper, the so-called rain profiling...
متن کاملHydrometeor classification methodology for C-band polarimetric radars
Classification of hydrometeors has a wide variety of applications such as validation of cloud microphysical models, choice of algorithm for precipitation estimation and evaluation of assumptions made in the precipitation retrieval processes as well as validation of space borne observations. Dual-polarization radar measurements are sensitive to hydrometeors properties such as size, shape, phase ...
متن کاملHeavy Rainfall Monitoring by Polarimetric C-Band Weather Radars
Piemonte region, in the north-western Italy, is characterized by complex orography and Mediterranean influence that often causes extreme rainfall event, during the warm season. Although the region is monitored by a dense gauge network (more than one gauge per 100 km 2 ), the ground measurements are often inadequate to properly observe intense and highly variable precipitations. Polarimetric wea...
متن کاملThe Estimation of Snowfall Rate Using Visibility
The relationship between liquid equivalent snowfall rate and visibility is investigated using data collected at the National Center for Atmospheric Research Marshall Snowfall Test Site during two winter field seasons and using theoretical relationships. The observational data include simultaneous liquid equivalent snowfall rate, crystal types, and both automated and manual visibility measuremen...
متن کاملAssessment of polarimetric rain rate algorithms at C-band frequencies
The purpose of this paper is to evaluate the performance of different polarimetric rainfall estimation algorithms at C-band frequencies. The polarimetric rainfall algorithms are obtained using a wide range of measured drop size distributions with an optical disdrometer in the UK. A dense network of raingauges was used to validate the polarimetric rainfall estimates and the overall results were ...
