The D configuration requires several datasets, many of which are grid-dependent. The following example is for the supported T42_gx1v3 grid. When building the D configuration with datm5, the following files will be copied to the $EXEROOT directory from the input data directory:
$EXEROOT/atm/0005-01.nc $EXEROOT/cpl/map_T42_to_gx1v3_aave_da_010709.nc $EXEROOT/cpl/map_T42_to_gx1v3_bilin_da_010710.nc $EXEROOT/cpl/map_gx1v3_to_T42_aave_da_010709.nc $EXEROOT/cpl/map_r05_to_gx1v3_roff_smooth_010718.nc $EXEROOT/ice/data.domain.grid $EXEROOT/ice/data.domain.kmt $EXEROOT/ice/rest/iced.0001-01-01.gx1v3 $EXEROOT/lnd/lsmh_0005.nc $EXEROOT/ocn/domain.gx1v3_010723.nc $EXEROOT/ocn/sst.str_970911.nc
Only the first month of CCM forcing (0005-01.nc)is provided with this release for the T42 grid. The number of atmospheric netCDF forcing files necessary will depend on the namelist options chosen in datm.setup.csh. See section 4.1.3.3 for information on these options.
To run the M configuration with latm5 and the ocean mixed layer within the ice model on the T62_gx1v3 grid using one year of forcing data from 1985, the following files will be copied to the $EXEROOT directory:
$EXEROOT/atm/dn10.1985.nc $EXEROOT/atm/lwdn.1985.nc $EXEROOT/atm/prec.1985.nc $EXEROOT/atm/q_10.1985.nc $EXEROOT/atm/swdn.1985.nc $EXEROOT/atm/swup.1985.nc $EXEROOT/atm/t_10.1985.nc $EXEROOT/atm/u_10.1985.nc $EXEROOT/atm/v_10.1985.nc $EXEROOT/cpl/map_T62_to_gx1v3_aave_da_010806.nc $EXEROOT/cpl/map_T62_to_gx1v3_bilin_da_010806.nc $EXEROOT/cpl/map_gx1v3_to_T62_aave_da_010806.nc $EXEROOT/cpl/map_r05_to_gx1v3_roff_smooth_010718.nc $EXEROOT/ice/data.domain.grid $EXEROOT/ice/data.domain.kmt $EXEROOT/ice/oceanmixed_ice.nc $EXEROOT/ice/rest/iced.0001-01-01.gx1v3 $EXEROOT/lnd/lsmh_0016.nc $EXEROOT/ocn/domain.gx1v3_010723.nc $EXEROOT/ocn/sst.str_970911.nc
Note that this is only one particular example of using latm5. See the data model User's Guide for more information. The input files required for CSIM4 are as follows:
Depending on ${ICE_GRID} selected in the main driver script,
the appropriate global* files will be copied and renamed in $EXEROOT/ice.
The restart file will be copied to $EXEDIR/rest which is set in the
ice setup script. Currently, only gx3 and gx1v3 grids are supported for the ice
and ocean models.
To run the prescribed ice model, an additional data file is necessary and depends on the chosen grid. For the high resolution grid:
The first 2 years of the dataset are climatology. The third year changes
smoothly until it reaches 1978, the beginning of monthly observed values.
If PRESCRIBED_ICE_CLIM = .true. at the top of ice.setup.csh,
the first year of climatological data will be used. Seventeen years of
consecutive AMIP forcing will be used if PRESCRIBED_ICE_CLIM = .false..
Another data file is necessary to use the ocean mixed layer within the ice model, depending on the specified grid:
This file is renamed oceanmixed_ice.nc when it is copied into $EXEROOT/ice.
