RISObtaining Best Estimates for the Microphysical and Radiative Properties of Tropical Ice Clouds from TWP-ICE In Situ Microphysical Observations
Publisher: American Meteorological Society
Abstract: est estimates of the bulk microphysical and radiative properties (ice water content, visible extinction, effective radius, and total concentration) are derived for three case studies of tropical ice clouds sampled during ...
The Role of Spaceborne Millimeter-Wave Radar in the Global Monitoring of Ice Cloud
Publisher: American Meteorological Society
Abstract: The purpose of this paper is to assess the potential of a spaceborne 94-GHz radar for providing useful measurements of the vertical distribution and water content of ice clouds on a global scale. Calculations of longwave ...
Ice Crystal Sizes in High Ice Water Content Clouds. Part II: Statistics of Mass Diameter Percentiles in Tropical Convection Observed during the HAIC/HIWC Project
Publisher: American Meteorological Society
Abstract: AbstractHigh ice water content (IWC) regions in mesoscale convective systems (MCSs) are a potential threat to commercial aviation, as they are suspected to cause in-service engine power-loss events and air data probe ...
Nasa's Tropical Cloud Systems and Processes Experiment
Publisher: American Meteorological Society
Abstract: In July 2005, the National Aeronautics and Space Administration investigated tropical cyclogenesis, hurricane structure, and intensity change in the eastern North Pacific and western Atlantic using its ER-2 high-altitude ...
The DOE ARM Aerial Facility
Publisher: American Meteorological Society
Abstract: tment of Energy Atmospheric Radiation Measurement (ARM) program is a climate research user facility operating stationary ground sites that provide long-term measurements of climate-relevant properties, mobile ground- and ...
Mixed-Phase Clouds: Progress and Challenges
Publisher: American Meteorological Society
Abstract: AbstractMixed-phase clouds represent a three-phase colloidal system consisting of water vapor, ice particles, and coexisting supercooled liquid droplets. Mixed-phase clouds are ubiquitous in the troposphere, occurring at ...
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 ...
The Mixed-Phase Arctic Cloud Experiment
Publisher: American Meteorological Society
Abstract: The Mixed-Phase Arctic Cloud Experiment (M-PACE) was conducted from 27 September through 22 October 2004 over the Department of Energy's Atmospheric Radiation Measurement (ARM) Climate Research Facility (ACRF) on the North ...
Secondary Ice Production: Current State of the Science and Recommendations for the Future
Publisher: American Meteorological Society
Abstract: easured ice crystal concentrations in natural clouds at modest supercooling (temperature ~>?10°C) are often orders of magnitude greater than the number concentration of primary ice nucleating particles. Therefore, it has ...
