radiances and those computed based on the NWP output of the atmospheric state. In the absence of cloud absorption and atmospheric scattering from precipitation an accurately parameterized radiative transfer model was used to assimilate satellite measurements into global NWP models for clear atmospheric conditions (e.g., Eyre 1989 ; Garand et al. 2001 ). However, in order to utilize the full capabilities of AMSU and other advanced instruments, which includes all weather conditions, an accurate

-dimensional radiative transfer (3DRT) effects are potentially important; horizontal photon transport can override the explicit connection of the shortwave radiation field to the underlying cloud microphysics. The net cloud radiative impact from the aerosol indirect effects is not intuitively obvious without a full radiative transfer calculation. A useful measure of a cloud’s sensitivity to modification by aerosol is the cloud susceptibility S ( Platnick and Twomey 1994 ): where N d is the cloud droplet number

1. Introduction Radiative transfer modeling is crucial in determining the radiation budget for weather/climate prediction models and for remote sensing of the earth and atmosphere. Demands for accurate radiation modeling have accompanied recent advances in finescale atmospheric modeling to resolve clouds, and in satellite measurements by sensors with improved spatial and spectral resolution. Monte Carlo photon transport algorithms are often employed to simulate realistic radiation processes

Wielicki 1984 ; McKee and Klehr 1978 ). Incorporating information about cloud scale and spatial distribution into cloud and radiation modeling has long been recognized as an important step toward an improved understanding of atmospheric radiative transfer (e.g., Plank 1969 ; Kuhn 1978 ; Stephens and Platt 1987 ). A statistical representation of the cloud field such as that used in stochastic theory may be a useful approach to modeling broken or scattered clouds ( Stephens 1988 ; Malvagi and
