Newbies guide to running NorESM
The purpose of this page is to be able to set up and run the model within 15 minutes. For more advanced configuration, please consult http://www.cesm.ucar.edu/models/ccsm4.0/ccsm_doc/ug.pdf
This guide assumes that you have properly checked out the model to some directory which will call $NORESM. This directory will contain subdirectories “models” and “scripts”.
Go to scripts directory
cd $NORESM/scripts
Create the case
./create_newcase -case ../cases/casename/ -mach machinename -res f19_g16 -compset compsetname
(where casename, machinename and compsetname are user input. Res is imodel resolution. The user can not give any resolution since input data are not prepared for any resolution in NorESM.)
Configure the case
cd $NORESM/cases/casename
./configure -case
After these two commands, the case is configured
Build the case
./casename.machinename.build
Run the case
qsub casename.machinename.run
Example
There are already several pre-defined compsets. They all have long and short names. As and example we can use the compset N_2000_AEROSLO_CN (with short name N2000AERCN). Thus a valid command on the machine hexagon is:
./create_newcase -case ../cases/N2000test/ -mach hexagon -res f19_g16 -compset N2000AERCN
Important files
The most important files to understand in your case-directory are:
- env_run.xml (model run type, how long time to run etc)
- env_conf.xml (model configuration)
