Radiative Transfer in Cirrus Clouds. Part III: Light Scattering by Irregular Ice Crystals
Publisher: American Meteorological Society
Abstract: A new Monte Carlo/geometric ray-tracing method has been developed for the computation of the scattering, absorption, and polarization properties of ice crystals with various irregular structure, including hollow columns, ...
The Effects of Small Ice Crystals on Cirrus Infrared Radiative Properties
Publisher: American Meteorological Society
Abstract: Using a model that combines single-scattering properties for spheroidal and hexagonal ice crystals, the thermal infrared radiative properties of cirrus clouds have been investigated. Infrared scattering and absorption ...
Nephelometer Measurements of the Asymmetry Parameter, Volume Extinction Coefficient, and Backscatter Ratio in Arctic Clouds
Publisher: American Meteorological Society
Abstract: A new instrument, a cloud integrating nephelometer (CIN), was used on the University of Washington?s CV-580 research aircraft to measure the asymmetry parameter (g), volume scattering coefficient, and backscatter ratio in ...
A Polarized Delta-Four-Stream Approximation for Infrared and Microwave Radiative Transfer: Part I
Publisher: American Meteorological Society
Abstract: The delta-four-stream polarized (vector) thermal radiative transfer has been formulated and numerically tested specifically for application to satellite data assimilation in cloudy atmospheres. It is shown that for thermal ...
Remote Sensing of Cirrus Cloud Particle Size and Optical Depth Using Polarimetric Sensor Measurements
Publisher: American Meteorological Society
Abstract: This paper presents a conceptual approach toward the remote sensing of cirrus cloud particle size and optical depth using the degree of polarization and polarized reflectance associated with the first three Stokes parameters, ...
Remote Sounding of the Tropical Cirrus Cloud Temperature and Optical Depth Using 6.5 and 10.5 μm Radiometers during STEP
Publisher: American Meteorological Society
Abstract: A dual-channel retrieval technique involving the water vapor band at 6.5 ?m and the window region at 10.5 gm has been developed to infer the temperature and emissivity of tropical anvils. This technique has been applied ...
Remote Sounding of Cirrus Cloud Optical Depths and Ice Crystal Sizes from AVHRR Data: Verification Using FIRE II IFO Measurements
Publisher: American Meteorological Society
Abstract: Using the data obtained from the Advanced Very High Resolution Radiometer (AVHRR) 3.7-µm and 10.9-µm channels, a retrieval scheme has been developed to simultaneously infer cirrus cloud optical depth and mean effective ice ...
