The Effect of Radar Pulse Length on Cloud Reflectivity Statistics
Publisher: American Meteorological Society
Abstract: When observing clouds with radars, there are a number of design parameters, such as transmitted power, antenna size, and wavelength, that can affect the detection threshold. In making calculations of radar thresholds, also ...
Mesoscale and Microscale Structure of Cirrus Clouds: Three Case Studies
Publisher: American Meteorological Society
Abstract: The structure and composition of three basic cirrus cloud types are examined through coordinated aircraft and ground-based polarization lidar and radar measurements. The cloud systems consist of a multilayered orographic ...
Distributions of Liquid, Vapor, and Ice in an Orographic Cloud from Field Observations
Publisher: American Meteorological Society
Abstract: The phase distribution of the water mass of a cold orographic cloud into vapor, liquid, and ice is calculated from measurements made from an instrumented aircraft. The vapor values are calculated from thermodynamic ...
Arctic Cloud Microphysics Retrievals from Surface-Based Remote Sensors at SHEBA
Publisher: American Meteorological Society
Abstract: An operational suite of ground-based, remote sensing retrievals for producing cloud microphysical properties is described, assessed, and applied to 1 yr of observations in the Arctic. All measurements were made in support ...
Daytime Global Cloud Typing from AVHRR and VIIRS: Algorithm Description, Validation, and Comparisons
Publisher: American Meteorological Society
Abstract: Three multispectral algorithms for determining the cloud type of previously identified cloudy pixels during the daytime, using satellite imager data, are presented. Two algorithms were developed for use with 0.65-, 1.6-/3.75-, ...
Arctic Mixed-Phase Cloud Properties Derived from Surface-Based Sensors at SHEBA
Publisher: American Meteorological Society
Abstract: Arctic mixed-phase cloud macro- and microphysical properties are derived from a year of radar, lidar, microwave radiometer, and radiosonde observations made as part of the Surface Heat Budget of the Arctic Ocean (SHEBA) ...
Variability of Cloud Vertical Structure during ASTEX Observed from a Combination of Rawinsonde, Radar, Ceilometer, and Satellite
Publisher: American Meteorological Society
Abstract: The macroscale cloud vertical structure (CVS), including cloud-base and -top heights and layer thickness, and characteristics of multilayered clouds, is studied at Porto Santo Island during the Atlantic Stratocumulus ...
Evaluation of Radar Reflectivity–Based Estimates of Water Content in Stratiform Marine Clouds
Publisher: American Meteorological Society
Abstract: The performance of radar reflectivity (Ze)?based relations for retrievals of marine stratiform cloud liquid water content (LWC) is evaluated by comparing liquid water path (LWP) estimates from microwave radiometers with ...
Cloud Boundary Statistics during FIRE II
Publisher: American Meteorological Society
Abstract: An 8-mm wavelength radar, 3-mm wavelength radar, and 10.6-µm wavelength lidar operated side by side in vertically pointing mode during the First ISCCP Regional Experiment (FIRE II). This data collection mode yielded detailed ...
