Differential Doppler Velocity: A Radar Parameter for Characterizing Hydrometeor Size Distributions
Observations of Doppler-resolved spectra of differential radar reflectivity provide estimates of particle shapes as a function of their terminal velocity, and they can be derived by having the antenna at a significant elevation angle. Turbulence tends to smear out the details of the actual spectra observed, but the difference in the mean values of velocity using horizontal and vertical polariza...
متن کاملCharacterizing the Radar Backscatter-Cross-Section Sensitivities of Ice-Phase Hydrometeor Size Distributions via a Simple Scaling of the Clausius–Mossotti Factor
One of the challenges that limit the amount of information that can be inferred from radarmeasurements of ice and mixed-phase precipitating clouds is the variability in ice mass within hydrometeors. The variable amount of ice mass within particles of a given size drives further variability in single-scattering properties that results in uncertainties of forward-modeled remote sensing quantities...
متن کاملWind velocity observation with a CW Doppler radar
We study the problem of gathering information about wind velocity from continuous-wave clear-air Doppler radar measurements. The radar is assumed to be a monostatic fixed-frequency Doppler radar, and the wind velocity as well as the reflectivity are modeled as random fields with statistical parameters depending on the altitude. We seek to reconstruct the hodograph curve of the wind profile, i.e...
متن کاملAn Improved Doppler Parameter Estimator for Synthetic Aperture Radar
To achieve a high quality synthetic aperture radar (SAR) image, the motion caused by the radar and/or the moving target needs be compensated for coherent processing, and this requires the accurate estimation of the Doppler parameters of the received signals. A new, approximate, maximum likelihood (ML) estimator in the time domain is obtained recently to jointly estimate the Doppler parameters, ...
متن کاملA Dual-Polarization Radar Hydrometeor Classification Algorithm for Winter Precipitation
The purpose of this study is to demonstrate the use of polarimetric observations in a radar-based winter hydrometeor classification algorithm. This is accomplished by deriving bulk electromagnetic scattering properties of stratiform, cold-season rain, freezing rain, sleet, dry aggregated snowflakes, dendritic snow crystals, and platelike snow crystals at X-, C-, and S-band wavelengths based on ...
