The prep-ic-icmcl-compo.sh script (henceforth: prep script) carries out 4 tasks:
- Create Creates a destination directory $AC_IC_DIR which serves as a staging area for all initial and boundary conditions required for the forecast experiment. Symbolic links will point later from inside the experiment run directory to these files.
- Copy Copies the physical/meteorological initial conditions files that must be specific to the experiment start date from $OIFS_INIDATA_DIR to the new $AC_IC_DIR. If these files cannot be found then they are createdan attempt is made to create them from files found in the $MET_IC_DIR directory.
- Copy Copies the physical boundary conditions file ICMCL{exp}INIT (SSTs, albedos, etc) from $OIFS_INIDATA_DIR to $AC_IC_DIR and if necessary truncate to length of experiment duration.
- Copy Copies the chemistry initial and boundary conditions file (emission fluxes, deposition velocities) ICMCL-INIT-COMPO from $OIFS_INIDATA_DIR to $AC_IC_DIR. If this file cannot be found it will be created.

with start_date and end_date having the format YYYY-MM-DD.
In the examples above for a 2-day forecast, the syntax should be: be ./prep-ic-icmcl-compo.sh 2010-01-01 2010-01-03 to run generate the data for 48 hours from 1st January 2010.
Running the prep script will take a few minutes and will result in new data which that will be written to folder $AC_IC_DIR, by default this location is $SCRATCH/43r3/experiments/{exp}/chem_ic.
This folder serves as a staging area for the initial experiment and boundary conditions data and if the target files in $AC_IC_DIR already exist in this destination then they they will not be overwritten.
...
The actual forecast experiment will be carried out inside the run directory. By default this is set to $SCRATCH/43r3/experiments/${exp}/rundirruns/.
