NASA Ames Mars Global Climate Model(ARC-18710-1)

We present the NASA Ames Mars Global Climate Model (NASA Ames MGCM) physics submodule for public release. This submodule is intended to work with the Finite-Volume dynamical core and cubed-sphere grid (FV3) developed by NOAA/GFDL and includes several of the Mars physics packages employed by the NASA Ames Legacy Mars Global Climate Model to simulate the Martian climate. The physics packages include: model surface properties such as thermal inertia and albedo; a ground and subsurface temperature scheme; a planetary boundary layer (PBL) scheme; water and carbon dioxide sublimation/condensation physics; a 2-moment dust and water-ice cloud microphysical scheme; several methods for the treatment of dust including an analytically prescribed dust field, dust lifting matched to a prescribed map, and fully-interactive lifting; and a two-stream radiative transfer code based on correlated-Ks.
