RISStratocumulus Cloud Field Reflected Fluxes: The Effect of Cloud Shape
Publisher: American Meteorological Society
Abstract: Reflected fluxes are calculated for stratocumulus cloud fields as a function of sky cover, cloud aspect ratio, and cloud shape. Cloud liquid water volume is held invariant as cloud shape is varied so that the results can ...
A Radiative Parameterization of Stratocumulus Cloud Fields
Publisher: American Meteorological Society
Abstract: A parameterization scheme is presented which allows the calculation of radiative reflected fluxes from a stratocumulus cloud field. The scheme is based upon plane-parallel calculations, such as delta-Eddington, and a simple ...
Marine Stratocumulus Cloud Fields off the Coast of Southern California Observed Using LANDSAT Imagery. Part II: Textural Analysis
Publisher: American Meteorological Society
Abstract: Statistical measures of the spatial distributions of gray levels (cloud reflectivities) are determined for LANDSAT Multispectral Scanner digital data. Textural properties for twelve stratocumulus cloud fields, seven cumulus ...
Structural and Textural Characteristics of Cirrus Clouds Observed Using High Spatial Resolution LANDSAT Imagery
Publisher: American Meteorological Society
Abstract: Twelve cirrus scenes are analyzed to determine textural and structural features using LANDSAT imagery. The main structural characteristics are: 1) cirrus cloud size distributions obey a power law, with larger cloud cells ...
Analysis of Spatial Inhomogeneities in Cumulus Clouds Using High Spatial Resolution Landsat Data
Publisher: American Meteorological Society
Abstract: Aircraft observations and high resolution Landsat Multispectral Scanner digital data are used to determine the sizes of spatial inhomogeneities (?holes?) in cumulus clouds. The majority of holes are found near cloud edges, ...
The Effects of Very Large Drops on Cloud Absorption. Part I: Parcel Models
Publisher: American Meteorological Society
Abstract: In an effort to bring more realism cloud-radiation calculations, arising-parcel model of cloud microphysics and a 191 waveband model of atmospheric radiation (ATRAD) have been brought to bear on the problem of cloud ...
Prediction of Quasi-Periodic Oscillations in Radiation Fogs. Part I: Comparison of Simple Similarity Approaches
Publisher: American Meteorological Society
Abstract: There is considerable controversy in the literature concerning fog formation. One set of observations suggests that fog forms during a lull in turbulence, white another set of observations suggests that increased turbulence ...
Estimation of Cirrus and Stratus Cloud Heights Using Landsat Imagery
Publisher: American Meteorological Society
Abstract: A new method based upon high-spatial-resolution imagery is presented that matches cloud and shadow regions to estimate cirrus and stratus cloud heights. The distance between the cloud and the matching shadow pattern is ...
Marine Stratocumulus Cloud Fields off the Coast of Southern California Observed Using LANDSAT Imagery. Part I: Structural Characteristics
Publisher: American Meteorological Society
Abstract: The structural characteristics of stratocumulus cloud fields off the coast of southern California are investigated using LANDSAT Multispectral Scanner (MSS) imagery. Twelve scenes in this area are examined along with three ...
Polar Cloud and Surface Classification Using AVHRR Imagery: An Intercomparison of Methods
Publisher: American Meteorological Society
Abstract: Six Advanced Very High-Resolution Radiometer local area coverage (AVHPR LAC) arctic scenes are classified into ten classes. These include water, solid sea ice, broken sea ice, snow-covered mountains, snow-free land, and ...
