RISThe Reliability of the PMS FSSP in the Presence of Small Ice Crystals
Publisher: American Meteorological Society
Abstract: The performance of measurement systems for small ice crystals is an important issue because of the need to characterize cirrus cloud microphysics for climate research. In a cloud formed of small quasi-spherical ice particles, ...
A Comparison of In-Cloud Measurements Obtained with Six PMS 2D-C Probes
Publisher: American Meteorological Society
Abstract: During a preparatory experiment (PREICE) for the field campaign of the International Cirrus Experiment (ICE), six different Particle Measuring Systems (PMS) 2D-C probes belonging to five research organizations were ...
Light Scattering by Single Natural Ice Crystals
Publisher: American Meteorological Society
Abstract: During the South Pole Ice Crystal Experiment, angular scattering intensities (ASIs) of single ice crystals formed in natural conditions were measured for the first time with the polar nephelometer instrument. The microphysical ...
Development of a Detailed Microphysics Cirrus Model Tracking Aerosol Particles’ Histories for Interpretation of the Recent INCA Campaign
Publisher: American Meteorological Society
Abstract: Cirrus clouds play an important role in the earth?s energy balance. To quantify their impact, information is needed on their microstructure and more precisely on the number and size of the ice crystals. With the anthropogenic ...
Assessment of Cirrus Cloud Optical and Microphysical Data Reliability by Applying Statistical Procedures
Publisher: American Meteorological Society
Abstract: A methodology of employing statistical procedures, specifically the principal component analysis (PCA) technique, to assess cirrus cloud data reliability is described. The approach is demonstrated by an example of a study ...
Microphysical and Optical Properties of Cirrus and Contrails: Cloud Field Study on 13 October 1989
Publisher: American Meteorological Society
Abstract: During the intensive International Cirrus Experiment conducted over the North Sea during fall 1989, natural cirrus and contrail-induced cirrus were analyzed from in situ and remote sensing measurements (lidar and infrared ...
In Situ Observation of Cirrus Scattering Phase Functions with 22° and 46° Halos: Cloud Field Study on 19 February 1998
Publisher: American Meteorological Society
Abstract: Observations of halos and related phenomena due to ice crystals are commonly reported from ground observations and presented in the literature. Nevertheless, ice crystal characteristics have only been poorly documented ...
Microphysical and Optical Properties of Atmospheric Ice Crystals at South Pole Station
Publisher: American Meteorological Society
Abstract: In early February 2001 (during the austral summer), over 900 000 digital images of ice crystals were recorded at the South Pole using two ground-based cloud particle imagers (CPIs). Of these, 721 572 crystals >50 ?m were ...
Comparison of Airborne In Situ, Airborne Radar–Lidar, and Spaceborne Radar–Lidar Retrievals of Polar Ice Cloud Properties Sampled during the POLARCAT Campaign
Publisher: American Meteorological Society
Abstract: his study illustrates the high potential of RALI, the French airborne radar?lidar instrument, for studying cloud processes and evaluating satellite products when satellite overpasses are available. For an Arctic nimbostratus ...
