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.)

To see a list of available composets type ./create_newcase -list

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)
