Running the prep script will take a few minutes and result in new data written to folder chem_ic. Afterwards the platform-specific job wrapper script can be executed to submit the model experiment job to the batch scheduler.

We begin with a batch job to run OpenIFS/AC without restarts and without XIOS. For this purpose we modify run-cca.job:
- in run-cca.job delete the accounting PBS header line:
#PBS -l EC_billing_account=nlchekli
Edit the following lines in file config.h:
- PLATFORM='damk' or 'atos-intel' (depending on Cray or Atos)
- OIFS_DATA_DIR= (set to your oifs data dir)
- ICMCLDIR= (set to where ICMCL directory has previously been extracted to
- OIFS_INIDATA_DIR= path_to_.../INITIAL_CONDITIONS/T255L91-tm5-none
- MET_IC_DIR= path_to_...ICMCL/aabg/2010010100
Prepare initial conditions for chemistry:
- the following script requires the substring and the grib_get commands: On the Cray load modules sms and eccodes (not clear for Atos?)
- run script
prep-ic-icmcl-compo.sh 2010-01-01 2010-01-03(if startdate and enddate are not given 2010-01-01 + 2 days fclength is used as default)
(this command takes a few minutes to complete, check $PROGDIR as this presumes the location of timeint.exe) - during the above process an experiment directory is created:
$SCRATCH/43r3/experiments/{expid}/chem_ic/with default expid=abcd (contains about 1.7 GB data)
Following these steps:
