The Polarization Lidar Technique for Cloud Research: A Review and Current Assessment
Publisher: American Meteorological Society
Abstract: The development of the polarization lidar field over the past two decades is reviewed, and the current cloud-research capabilities and limitations are evaluated. Relying on fundamental scattering principles governing the ...
Deep Orographic Cloud Structure and Composition Derived from Comprehensive Remote Sensing Measurements
Publisher: American Meteorological Society
Abstract: Coordinated polarization lidar, Ku-band radar and dual-channel microwave radiometer observations of a deep orographic cloud system were collected from a mountain-base site in northwestern Colorado as part of the Colorado ...
Ice Cloud Content from Radar Reflectivity
Publisher: American Meteorological Society
Abstract: The ice equivalent radar reflectivity factor (Zi = 5.3Ze) is found from previous measurements to be related to the precipitation rate (R mm h?1) and ice mass content (M, g m?3) of ice crystal clouds by R = 0.067Zi0.804 and ...
Air-Truth Lidar Polarization Studies of Orographic Clouds
Publisher: American Meteorological Society
Abstract: The results of a field program of coordinated lidar and aircraft observations of orographically induced clouds are reported. An evaluation of polarization diversity lidar for cloud physics research applications on the basis ...
The Continuous-Impactor-Replicator for Laboratory Cloud Composition Analysis
Publisher: American Meteorological Society
Abstract: The design and operation of a cloud-sampling device for laboratory applications is described. The cloud particles are collected in a continuous or sequential fashion by impaction, with volatile particle shape and size ...
An Initial Application of Polarization Lidar for Orographic Cloud Seeding Operations
Publisher: American Meteorological Society
Abstract: Ground-based polarization lidar measurements have been obtained in conjunction with a commercial cloud seeding program to evaluate the potential of pulsed laser remote sensing techniques for increasing the effectiveness ...
Depolarization of Laser Light Backscattered by Artificial Clouds
Publisher: American Meteorological Society
Abstract: An apparatus is described which measures the linear depolarization ratios of vertically polarized laser light (6328 Å) backscattered by mixed phase particle clouds grown in a laboratory cold chamber. Variations in linear ...
Polarization Diversity Lidar Returns from Virga and Precipitation: Anomalies and the Bright Band Analogy
Publisher: American Meteorological Society
Abstract: Polarization measurements have been obtained with lidar from ice virga and precipitation. Linear depolarization ratios are characteristically near 0.5 for the ice phase, but can display significantly higher values under ...
