PUBLIC ROUTINES
call atmosphere_init ( Time_init, Time, Time_step )
DESCRIPTION
Initialization call for running the bgrid dynamical with the
Held-Suarez GCM forcing.
INPUT
Time_init The base (or initial) time for the experiment.
The base time is usually subtracted from the current time
when outputting time in diagnostic routines.
[time_type]
Time The current time. [time_type]
Time_step The atmospheric model/physics time step. [time_type]
call atmosphere_end
DESCRIPTION
Termination call for the bgrid dynamical with Held-Suarez
GCM forcing. There are no arguments to this routine.
call atmosphere ( Time )
DESCRIPTION
Advances the B-grid prognostic variables one time step forward.
The dynamical core, Held-Suarez forcing, diagnostics, and time
differencing are all called. This routine should only be called
once per time step.
INPUT
Time The current time. [time_type]
NOTE
The prognostic variables are stored in a private data structure
(i.e., derived-type variable) defined in the specification section
of this module.
---------------------------------------------------------------------
call get_atmosphere_axes ( axes )
OUTPUT
axes Axis identifiers for the atmospheric grids as returned by the
diagnostics manager. The size of axes must be: 1 <= size(axes) <= 4.
The axes returned are ordered: (/ x, y, p_full, p_half /).
[integer, dimension(:)]
call atmosphere_resolution ( nlon, nlat [, global] )
DESCRIPTION
Returns the resolution of compute domain for either the
current processor or the global domain.
OUTPUT
nlon The number of longitude points in the compute domain.
[integer]
nlat The number of latitude points in the compute domain.
[integer]
OPTIONAL INPUT
global Flag that specifies whether the returned compute domain size is
for the global grid (TRUE) or for the current processor (FALSE).
[logical, default: FALSE]
call atmosphere_boundary ( blon, blat [, global] )
DESCRIPTION
Returns the grid box edges of compute domain for either the
current processor or the global domain.
OUTPUT
blon The west-to-east longitude edges of grid boxes (in radians).
[real, dimension(nlon+1)]
blat The south-to-north latitude edges of grid boxes (in radians).
[real, dimension(nlat+1)]
OPTIONAL INPUT
global Flag that specifies whether the returned grid box edges are
for the global grid (TRUE) or for the current processor (FALSE).
[logical, default: FALSE]
NOTE
The size of the output arguments, blon and blat, must be +1 more than the
output arguments for call atmosphere_resolution, nlon+1 and nlat+1, respectively.
