RISFrozen Hydrometeor Terminal Fall Velocity Dependence on Particle Habit and Riming as Observed by Vertically Pointing Radars
Publisher: American Meteorological Society
Depolarization Estimates from Linear H and V Measurements with Weather Radars Operating in Simultaneous Transmission–Simultaneous Receiving Mode
Publisher: American Meteorological Society
Abstract: Circular depolarization ratio (CDR) is a polarimetric parameter, which, unlike linear depolarization ratio (LDR), does not exhibit significant dependence on hydrometeor orientation and can be used for particle type ...
Theoretical Study of Radar Polarization Parameters Obtained from Cirrus Clouds
Publisher: American Meteorological Society
Abstract: A theoretical investigation of radar polarization parameters that characterize cloud ice backscattering is presented. The parameters considered were those commonly used in radar polarimetrics such as differential reflectivity ...
Attenuation-Based Estimates of Rainfall Rates Aloft with Vertically Pointing Ka-Band Radars
Publisher: American Meteorological Society
Abstract: An approach is suggested to retrieve low-resolution rainfall rate profiles and layer-averaged rainfall rates, Ra, from radar reflectivity measurements made by vertically pointing Ka-band radars. This approach is based on ...
The Use of CloudSat Data to Evaluate Retrievals of Total Ice Content in Precipitating Cloud Systems from Ground-Based Operational Radar Measurements
Publisher: American Meteorological Society
Abstract: n approach is described to retrieve the total amount of ice in a vertical atmospheric column in precipitating clouds observed by the operational Weather Surveillance Radar-1988 Doppler (WSR-88D) systems. This amount expressed ...
Polarimetric Radar–Based Estimates of Spatial Variability in Characteristic Sizes of Raindrops in Stratiform Rainfall
Publisher: American Meteorological Society
Abstract: olarimetric X-band radar measurements of differential reflectivity ZDR in stratiform rainfall were used for retrieving mean mass-weighted raindrop diameters Dm and estimating their spatial variability δDm at different ...
CloudSat Studies of Stratiform Precipitation Systems Observed in the Vicinity of the Southern Great Plains Atmospheric Radiation Measurement Site
Publisher: American Meteorological Society
Abstract: The spaceborne W-band (94 GHz) radar on board the CloudSat polar-orbiting satellite offers new opportunities for retrieving parameters of precipitating cloud systems. CloudSat measurements can resolve the vertical cross ...
Modeling Backscatter Properties of Snowfall at Millimeter Wavelengths
Publisher: American Meteorological Society
Abstract: Ground-based vertically pointing and airborne/spaceborne nadir-pointing millimeter-wavelength radars are being increasingly used worldwide. Though such radars are primarily designed for cloud remote sensing, they can also ...
Evaluating Polarimetric X-Band Radar Rainfall Estimators during HMT
Publisher: American Meteorological Society
Abstract: Different relations between rainfall rate R and polarimetric X-band radar measurables were evaluated using the radar, disdrometer, and rain gauge measurements conducted during the 4-month-long field experiment. The specific ...
A Method to Estimate Vertically Integrated Amounts of Cloud Ice and Liquid and Mean Rain Rate in Stratiform Precipitation from Radar and Auxiliary Data
Publisher: American Meteorological Society
Abstract: A method to retrieve total vertical amounts of cloud liquid and ice in stratiform precipitating systems is described. The retrievals use measurements from the vertically pointing Ka- and W-band cloud radars operated by the ...
