RISApplication of Dual-Frequency Millimeter-Wave Doppler Spectra for the Retrieval of Drop Size Distributions and Vertical Air Motion in Rain
Publisher: American Meteorological Society
Abstract: Millimeter-wave Doppler spectra obtained from the dual-frequency Cloud Profiling Radar System (CPRS) are used to retrieve both the drop size distribution and the vertical air motion in rain. CPRS obtains collocated spectra ...
Particle Size Estimation in Ice-Phase Clouds Using Multifrequency Radar Reflectivity Measurements at 95, 33, and 2.8 GHz
Publisher: American Meteorological Society
Abstract: Multifrequency radar measurements collected at 2.8 (S band), 33.12 (Ka band), and 94.92 GHz (W band) are processed using a neural network to estimate median particle size and peak number concentration in ice-phase clouds ...
Local Structure of the Convective Boundary Layer from a Volume-Imaging Radar
Publisher: American Meteorological Society
Abstract: The local structure and evolution of the convective boundary layer (CBL) are studied through measurements obtained with a volume-imaging radar, the turbulent eddy profiler (TEP). TEP has the unique ability to image the ...
Polarization Diversity Pulse-Pair Technique for Millimeter-WaveDoppler Radar Measurements of Severe Storm Features
Publisher: American Meteorological Society
Abstract: The Polarization Diversity Pulse-Pair (PDPP) technique can extend simultaneously the maximum unambiguous range and the maximum unambiguous velocity of a Doppler weather radar. This technique has been applied using a ...
Continental Stratus Clouds: A Case Study Using Coordinated Remote Sensing and Aircraft Measurements
Publisher: American Meteorological Society
Abstract: A continental stratus cloud layer was studied by advanced ground-based remote sensing instruments and aircraft probes on 30 April 1994 from the Cloud and Radiation Testbed site in north-central Oklahoma. The boundary layer ...
Doppler Radar Observations of Substorm-Scale Vortices in a Supercell
Publisher: American Meteorological Society
Abstract: Counterrotating 500-m-scale vortices in the boundary layer are documented in the right-moving member of a splitting supercell thunderstorm in northeastern Oklahoma on 17 May 1995 during the Verification of the Origins of ...
A Volume-Imaging Radar Wind Profiler for Atmospheric Boundary Layer Turbulence Studies
Publisher: American Meteorological Society
Abstract: This paper describes the turbulent eddy profiler (TEP), a volume-imaging, UHF radar wind profiler designed for clear-air measurements in the atmospheric boundary layer on scales comparable to grid cell sizes of large eddy ...
The Combined Sensor Program: An Air–Sea Science Mission in the Central and Western Pacific Ocean
Publisher: American Meteorological Society
Abstract: Twelve national research organizations joined forces on a 30-day, 6800 n mi survey of the Central and Tropical Western Pacific on NOAA's Research Vessel Discoverer. The Combined Sensor Program (CSP), which began in American ...
Measurements of Ocean Surface Stress Using Aircraft Scatterometers
Publisher: American Meteorological Society
Abstract: Scatterometer model functions that directly estimate friction velocity have been developed and are being tested with radar and in situ data acquired during the Surface Wave Dynamics Experiment (SWADE) of 1991. Ku-band and ...
