noresm2cmor is a FORTRAN based command line tool for post-processing NorESM output using the Climate Model Output Rewriter (cmor) libraries.

System, model, experiment and variable information are set in namelist files which noresm2cmor reads during its execution.

Download noresm2cmor with

 git clone https://github.com/NorESMhub/noresm2cmor

Set the CMOR_ROOT enviroment variable in your .bashrc. For example, if you clone the code to your home directory, then set

export CMOR_ROOT=~/noresm2cmor

# Change directory 
cd noresm2cmor/build/  

Make a copy of Makefile.nird_intel - e.g., Makefile.xxx - and customize your make file. IMPORTANT: The build of noresm2cmor requires the fortran version of the cmor-library (see https://pcmdi.github.io/cmor-site/download.htm for download instructions).

Build with

 make –f Makefile.xxx 

Change directory to noresm2cmor/scripts

Run installation script for grid data ./install_griddata.sh

Run installation script for input data sample ./install_sampledata.sh

Change directory to noresm2cmor/scripts

If install_griddata.sh not used, set path to grid data ./setpath_griddata.sh

If install_sampledata.sh not used, set path to sample data ./setpath_sampledata.sh

Set path to output folder ./install_cmorout.sh

Run the script workflow/cmorSetup.sh to setup namelist template:

$ ./cmorSetup.sh

 Usage:
 ./cmorSetup.sh \
  -c=[casename]     # e.g., NHIST_f19_tn14_20190625 \
  -m=[model]        # e.g., NorESM2-LM, NorESM2-MM, NorESM1-F,NorESM1-M \
  -e=[expid]        # e.g., historical, piControl, ssp126, omip2, etc \
  -v=[version]      # e.g., v20200702 \
  -y1=[year1]       # e.g., 1850 \
  -y2=[yearn]       # e.g., 2014 \
  -r=[realization]  # e.g., 1,2,3 \
  -p=[physics]      # e.g., 1,2,3 \
  -i=[ibasedir]     # path to model output. e.g., /projects/NS9560K/noresm/cases \
  -o=[obasedir]     # path to cmorized output. e.g., /projects/NSxxxxK/CMIP6/cmorout \%

For example,

./cmorSetup.sh -c=NFHISTnorpibc_aeroxidonly_03_f19_20200118 \
-m=NorESM2-LM \
-e=piClim-histaer \
-v=v20200702 \
-y1=1850 -y2=2014 \
-r=3 -p=2 \
-i=/projects/NS9560K/noresm/cases \
-o=/projects/NS9034K/CMIP6/.cmorout

Then under $CMOR_ROOT/namelists/CMIP6_${model}/${expid}, the namelists are configured under: ${version}/, and a script to submit the job is created cmor_${casename}.sh.

Check the settings in the script and namelist. One can start the cmorization by exectuting the script cmor_${casename}.sh
