Generating initial data overview
Initial conditions for the standard OpenIFS model can be generated using the OpenIFS Data Hub or alternatively they can be requested from the ECMWF OpenIFS support by email openifs-support@ecmwf.int. This provides initial experiment data and surface boundary conditions for the physical/meteorological NWP forecast model.
...
with start_date and end_date having the format YYYY-MM-DD. In the examples above, the syntax should be: ./prep-ic-icmcl-compo.sh 2010-01-01 2010-01-03 to run for 48 hours from 1st January 2010.
Running the prep script will take a few minutes and will result in new data which will be written to folder $AC_IC_DIR, by default $SCRATCH/43r3/experiments/{exp}/chem_ic. This folder serves as a staging area for the initial experiment data and if the target files already exist in this destination they they will not be overwritten.
