module atmos_model_mod
!-----------------------------------------------------------------------
!<OVERVIEW>
! Driver for the atmospheric model, contains routines to advance the
! atmospheric model state by one time step.
!</OVERVIEW>
!<DESCRIPTION>
! This version of atmos_model_mod has been designed around the implicit
! version diffusion scheme of the GCM. It requires two routines to advance
! the atmospheric model one time step into the future. These two routines
! correspond to the down and up sweeps of the standard tridiagonal solver.
! Most atmospheric processes (dynamics,radiation,etc.) are performed
! in the down routine. The up routine finishes the vertical diffusion
! and computes moisture related terms (convection,large-scale condensation,
! and precipitation).
! The boundary variables needed by other component models for coupling
! are contained in a derived data type. A variable of this derived type
! is returned when initializing the atmospheric model. It is used by other
! routines in this module and by coupling routines. The contents of
! this derived type should only be modified by the atmospheric model.
