Hydrometeor 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 کاملImplementations of Csu Hydrometeor Classification Scheme for C-band Polarimetric Radars
Dual-polarization radar measurements are sensitive to hydrometeor properties such as shape, phase state, and fall behaviour (Bringi and Chandrasekar 2001) so that they can be used for hydrometeor classification purposes. The differential reflectivity (Zdr) is sensitive to the shape and orientation of precipitation particles: it can discriminate rain from spherical hail. The linear depolarizatio...
متن کاملHydrometeor classification with a C-band polarimetric radar
The scattering of electromagnetic energy by hydrometeors forms the basis of radar meteorology. Knowledge of hydrometeor types can be very important in particular applications. The occurrence of mixed-phase conditions, especially the melting of snow and ice, impacts on the accuracy of radar-based precipitation estimation and the discrimination of rain and hail is often very important in severe w...
متن کاملA Theory-Based Hydrometeor Identification Algorithm for X-Band Polarimetric Radars
Although much work has been done at S band to automatically identify hydrometeors by using polarimetric radar, several challenges are presented when adapting such algorithms to X band. At X band, attenuation and non-Rayleigh scattering can pose significant problems. This study seeks to develop a hydrometeor identification (HID) algorithm for X band based on theoretical simulations using the T-m...
متن کاملA new polarimetric scheme for attenuation correction at C band
A long-standing problem of attenuation correction at shorter weather radar wavelengths can be efficiently resolved by using measurements of differential phase ΦDP if the radar is polarimetrically upgraded. Original polarimetric method for attenuation correction by Bringi et al. (1990) stipulates that the ratio αh between specific attenuation Ah and specific differential phase KDP does not vary ...
