The focus of the work done under this grant has been to couple global circulation models (in particular, the National Center for Atmospheric Research (NCAR) Community Climate Model Version 2 (CCM2)) to a land-surface model at a much finer mesh than that used for the atmospheric processes. The end objective has been to incorporate into the CHAMMP modeling system a state-of-the-art land model on a mesh independent of the atmospheric model resolution. Efforts have emphasized the following: development and graphical displays of the fine-mesh land surface boundary conditions; the data structures required to carry out integrations on the land fine-mesh; the physical parameterization required to diaggregate model precipitation; analyses of the NCAR 10-year control simulation of the frozen version of CM2/BATS; implementation of changes in the cloud optical properties to mitgate excess incident solar radiation and temperatures over middle latitudes in the Northern Hemisphere summer; prototype development of the CCM2/BASTS fine-mesh treatment
