RISAirflow about King Air Wingtip-Mounted Cloud Particle Measurement Probes
Publisher: American Meteorological Society
Abstract: Distortion of airflow around aircraft bodies can affect measurements made from these airborne platforms. In particular, particle sizes and concentrations can be in error, and ice crystals incorrectly classified as a result ...
A Review and Discussion of Processing Algorithms for FSSP Concentration Measurements
Publisher: American Meteorological Society
Abstract: The forward-scattering spectrometer probe (FSSP) is an optical particle counter widely used for the measurement of cloud droplet size distributions and concentration. Previous studies have identified operational limitations ...
A Method for Validating FSSP Measurements Using Observational Data
Publisher: American Meteorological Society
Abstract: A validation method of measurements from the forward-scattering spectrometer probe (FSSP) allowing preliminary analysis and verification of rough data is presented. It is based on the comparison of observed spectral ...
Icing Wind Tunnel Tests on the CSIRO Liquid Water Probe
Publisher: American Meteorological Society
Abstract: Wet wind tunnel tests have been Performed on several versions of the CSIRO probe designed for the airborne measurement of liquid water content. Four different controller units and 17 different Probe sensors (including ...
Comparison of Raindrop Size Distributions Measured by Radar Wind Profiler and by Airplane
Publisher: American Meteorological Society
Abstract: Wind profilers are radars that operate in the VHF and UHF hands and are designed for detecting the weak echoes reflected by the optically clear atmosphere. An unexpected application of wind profilers has been the revival ...
Comparison of CALIPSO-Like, LaRC, and MODIS Retrievals of Ice-Cloud Properties over SIRTA in France and Florida during CRYSTAL-FACE
Publisher: American Meteorological Society
Abstract: This study compares cirrus-cloud properties and, in particular, particle effective radius retrieved by a Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO)-like method with two similar methods using ...
An Evaluation of the Community Aerosol Inlet for the NCAR C-130 Research Aircraft
Publisher: American Meteorological Society
Abstract: Based on both in-flight measurements and a fluid dynamics model, airflow in the National Center for Atmospheric Research (NCAR) Community Aerosol Inlet (CAI) is similar to fully developed pipe flow. Distortions of the ...
Cloud Ice Properties: In Situ Measurement Challenges
Publisher: American Meteorological Society
Abstract: nderstanding the formation and evolution of ice in clouds requires detailed information on the size, shape, mass, and optical properties of individual cloud hydrometeors and their bulk properties over a broad range of ...
Performance of a Focused Cavity Aerosol Spectrometer for Measurements in the Stratosphere of Particle Size in the 0.06–2.0-µm-Diameter Range
Publisher: American Meteorological Society
Abstract: A focused cavity aerosol spectrometer aboard a NASA ER-2 high-altitude aircraft provided high-resolution measurements of the size of the stratospheric particles in the 0.06?2.0-µm-diameter range in flights following the ...
Aircraft Particle Inlets: State-of-the-Art and Future Needs
Publisher: American Meteorological Society
Abstract: Aircraft inlets connect airborne instruments for particle microphysical and chemical measurements with the ambient atmosphere. These inlets may bias the measurements due to their potential to enhance or remove certain ...
