Title:The effect of shape and spatial distribution of cumulus clouds on longwave irradiance
Publication:J. Atmos. Sci., 51, 2123-2136
Abstract:In the longwave part of the spectrum, clouds are generally modeled in GCMs as flat black plates. The truce effective cloud cover for trasmittance of infrared radiation may be larger or smaller than the fractional cloud cover normal to the surface because of emittance of radiation from the sides of clouds into the clear sky and

Abstract:The chord length distributions within a cloud and between clouds are considered. Such information is needed as input to certain statistical models of cloud-radiation interaction. Modeling the clouds as azimuthally symmetric ellipsoids, the authors find that the chord length distribution through a cloud of fixed size is proportional to the chord length. The proportionality constant depends upon the semiaxes

Abstract:A rapid analytical radiative transfer model for reflection of solar radiation in plane-parallel atmospheres is developed based on the Soboleve approach and the delta function transformation technique. A distinct advantage of this model over alternative two-stream solutions is that in addition to yielding the irradiance compoents, which turn out to

Title:The albedo of fractal stratocumulus clouds.
Publication:J. Atmos. Sci., 51, 2434-2455
Abstract:An increase in the planetary albedo of the earth-atmosphere system by only 10% can decrease the equilibrium surface temperature to that of the last ice age. Nevertheless, albedo biases of 10% or greater would be introduced into large regions of current climate models if clouds were given their observed liquid water amounts, because of the treatment of clouds as plane parallel.

Abstract:The effect on absorption in clouds of having an inhomogeneous distribution of droplets is shown to depend on whether one replaces a homogeneous cloud by an inhomogeneous cloud that has the same mean optical thickness, or one that has the same spherical albedo. For the purposes of general circulation model (GCMs), the more appropriate comparison is between homogeneous and inhomogeneous clouds that have the same spherical albedo, so that the radiation balance of the planet with space is maintained.

Title:Effective diameter in radiation transfer: General definition, applications, and limitations
Publication:J. Atmos. Sci., 59, 2330-2346.
Abstract:Although the use of an effective radius for radiation transfer calculations in water clouds has been common for many years, the export of this concept to ice clouds has been fraught with uncertainty, dur to the nonspherical shapes of the particles.
