On the Correlated k-Distribution Method for Radiative Transfer in Nonhomogeneous Atmospheres
Publisher: American Meteorological Society
Abstract: The correlated k-distribution method for radiative transfer in nonhomogeneous atmospheres is discussed in terms of the physical and mathematical conditions under which this method is valid. Two correlated conditions are ...
Parameterization of the Radiative Properties of Cirrus Clouds
Publisher: American Meteorological Society
Abstract: A new approach for parameterization of the broadband solar and infrared radiative properties of ice clouds has been developed. This parameterization scheme integrates in a coherent manner the δ-four-stream approximation ...
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, ...
Radiative Transfer in Cirrus Clouds. Part IV: On Cloud Geometry, Inhomogeneity, and Absorption
Publisher: American Meteorological Society
Abstract: The effects of cloud geometry and inhomogeneity on the radiative properties of cirrus clouds are investigated by using the successive orders of scattering (SOS) approach for radiative transfer. This approach is an integral ...
Interactions of Radiation, Microphysics, and Turbulence in the Evolution of Cirrus Clouds
Publisher: American Meteorological Society
Abstract: A two-dimensional cirrus cloud model has been developed to investigate the interaction and feedback of radiation, ice microphysics, and turbulence-scale turbulence, and their influence on the evolution of cirrus clouds. ...
Radiation Parameterization for Three-Dimensional Inhomogeneous Cirrus Clouds: Application to Climate Models
Publisher: American Meteorological Society
Abstract: A three-dimensional (3D) radiative transfer model has been developed to simulate the transfer of solar and thermal infrared radiation in inhomogeneous cirrus clouds. The model utilizes a diffusion approximation approach ...
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 ...
Simultaneous Determination of Aerosol and Thin Cirrus Optical Depths over Oceans from MODIS Data: Some Case Studies
Publisher: American Meteorological Society
Abstract: The importance of separating thin cirrus and aerosols from satellite remote sensing to produce broader and more accurate fields for the determination of respective radiative forcings is highlighted. This has been accomplished ...
A Coupled Atmosphere–Ocean Radiative Transfer System Using the Analytic Four-Stream Approximation
Publisher: American Meteorological Society
Abstract: A coupled atmosphere?ocean radiative transfer model based on the analytic four-stream approximation has been developed. It is shown that this radiation model is computationally efficient and at the same time can achieve ...
The Impact of Direct Aerosol Radiative Forcing on Surface Insolation and Spring Snowmelt in the Southern Sierra Nevada
Publisher: American Meteorological Society
Abstract: To understand the regional impact of the atmospheric aerosols on the surface energy and water cycle in the southern Sierra Nevada characterized by extreme variations in terrain elevation, the authors examine the aerosol ...
