A Variational Scheme for Retrieving Rainfall Rate and Hail Reflectivity Fraction from Polarization Radar (2007, methodology): “and so the normalization factor [denoted Nw by Bringi and Chandrasekar (2001)] is eliminated.”
Relations between radar reflectivity, liquid‐water content, and rainfall rate during the MAP SOP (2003, background): “An advantage of the Z–W and Z–R relationships over dual-polarization methods (Bringi and Chandrasekar 2001) is that they can be applied to radar echo regions where the re ectivities are weak and the dual-polarization signal is noisy.”
The Bias and Error in Moment Estimators for Parameters of Drop Size Distribution Functions: Sampling from Gamma Distributions (2006, background): “Another formulation of the gamma DSD, involving a normalized concentration parameter Nw (Bringi and Chandrasekar 2001) that replaces n1 or NT, has come into use:”
Evaluation of a New Polarimetrically Based Z–R Relation (2004, methodology): “Following Bringi and Chandrasekar (2001), the elements of the backscattering matrix S for Rayleigh–Gans scattering can be written in terms of the dipole moments (cid:97) , (cid:97) z and the canting angle (cid:102) as z 0 6 and (cid:76) h and (cid:76) (cid:121) are deﬁned as where Note that a and b…”
Close-Range Observations of Tornadoes in Supercells Made with a Dual-Polarization, X-Band, Mobile Doppler Radar (2007, methodology): “The parameters H and V reflectivity (ZH and ZV), ZDR, KDP, hv, and Doppler velocity mean and standard deviation (Doviak and Zrnic 1984; Bringi and Chandrasekar 2001) were computed after field opera-”
The Hydrometeor Classification Algorithm for the Polarimetric WSR-88D: Description and Application to an MCS (2009, methodology): “…5 0.1, DZ(t)DR 5 0.5 dB, SNR(Z) 5 SNR(Kdp) 5 0 dB, and SNR(Zdr) 5 SNR(rhv) 5 5 dB. (25) The choice of threshold parameters in (25) was based on a theoretical analysis of the measurement errors caused by low rhv and SNR (Bringi and Chandrasekar 2001; Melnikov and Zrni c 2007) and NBF (Ryzhkov 2007).”
Estimation of Raindrop Size Distribution Parameters from Polarimetric Radar Measurements (2002, methodology): “The speciﬁc differential phase can be expressed as where 0 is the free space propagation constant, and f f (cid:121) are the forward scatter amplitudes at horizontal and vertical polarization, respectively For Rayleigh–Gans scattering, (14) reduces where (cid:101) r is the dielectric constant and th”
Polarimetric Signatures in Supercell Thunderstorms (2008, methodology): “As the magnitude of HV decreases, the statistical errors and noisiness of the other polarimetric variables increase, degrading the quality of polarimetric data (Bringi and Chandrasekar 2001).”
