Final technical report for Treatment of cloud radiative effects in general circulation models
The objectives of our participation in the Atmospheric Radiation Measurement (ARM) program were (1) to improve GCM treatment of subgrid-scale variability of cloud-radiation interaction, and (2) to study the effect of variability on GCM climate simulations. Specifically, the studies focused on the development of a ''mosaic'' approach to parameterize the variability associated with cloud vertical ''geometric association'' and horizontal ''inhomogeneity''; and the evaluation and improvement of radiative effects of aerosols and layer clouds. These studies were conducted using the shortwave and longwave radiation and cloud parameterizations employed in the SUNY-Albany regional climate model and the NCAR-CCM3 global climate model. The measurements at the ARM Southern Great Plains were used to evaluate and improve these GCM parameterizations. In addition, we also used the cloud resolving model simulations to supplement the cloud statistics, in particular the cloud geometric association and vertical water/ice distribution.
