Retrieving Cloud Ice Water Content Using Millimeter- and Centimeter-Wavelength Radar Polarimetric Observables
Publisher: American Meteorological Society
Abstract: cattering properties of a large collection of pristine ice crystals at millimeter and centimeter wavelengths are calculated using the generalized multiparticle Mie method. Millimeter- and centimeter-wavelength radar ...
Use of X-Band Differential Reflectivity Measurements to Study Shallow Arctic Mixed-Phase Clouds
Publisher: American Meteorological Society
Abstract: icrophysical processes in shallow Arctic precipitation clouds are illustrated using measurements of differential reflectivity ZDR from the U.S. Department of Energy Atmospheric Radiation Measurement Program polarimetric ...
Polarimetric Radar Signatures of Dendritic Growth Zones within Colorado Winter Storms
Publisher: American Meteorological Society
Abstract: -band polarimetric radar observations of winter storms in northeastern Colorado on 20?21 February, 9 March, and 9 April 2013 are examined. These observations were taken by the Colorado State University?University of ...
X-Band Polarimetric and Ka-Band Doppler Spectral Radar Observations of a Graupel-Producing Arctic Mixed-Phase Cloud
Publisher: American Meteorological Society
Abstract: haracteristics of graupel in an Arctic deep mixed-phase cloud on 7 December 2013 were identified with observations from an X-band scanning polarimetric radar and a Ka-band zenith-pointing radar in conjunction with scattering ...
Linear Depolarization Ratios of Columnar Ice Crystals in a Deep Precipitating System over the Arctic Observed by Zenith-Pointing Ka-Band Doppler Radar
Publisher: American Meteorological Society
Abstract: his study demonstrates that linear depolarization ratio (LDR) values obtained from zenith-pointing Ka-band radar Doppler velocity spectra are sufficient for detecting columnar ice crystals. During a deep precipitating ...
What Can We Conclude about the Real Aspect Ratios of Ice Particle Aggregates from Two-Dimensional Images?
Publisher: American Meteorological Society
Abstract: simple numerical experiment was performed to investigate the result published in many papers that measurements indicate that aggregates may be well represented as oblate spheroids with mean aspect ratio (semiminor axis to ...
