How to run the regionally refined model (RRM)
When creating the regionally refined model (RRM) case, please refer to the steps in this article.
Step-by-step guide
- Check-out ACME : see Development Quick Guide for details.
- Create and build a new case from the scripts directory:
$ ./create_newcase -res conusx4v1_conusx4v1 -case $CASENAME -compset $COMPSET -mach $MACH -project $PROJECT
ACME v0 – an example for L30: $ ./create_newcase -case f1850c5_conusx4v1 -project 150001 -compset F1850C5 -res conusx4v1_conusx4v1 -mach skybridge
ACME v1 – an example for L72: $ ./create_newcase -case fFC5AV1C-04P2_conusx4v1 -project 150001 -compset FC5AV1C-04P2 -res conusx4v1_conusx4v1 -mach skybridge
- Edit env_mach_pes.xml as needed. For Sandia's skybridge machine, using 800 cores and 1 thread for each component runs at X.YZ simulated years per day.
- Edit env_run.xml as needed to specify the run-length.
- Set-up and build the case.
$ ./cesm_setup
$ ./$CASENAME.build
(When building a case for the first time, the script will look for the boundary and initial condition files which are located on the ACME data server. See ACME Input Data Repository.) - Edit the namelist files (i.e., user_nl_cam) for user-specified output settings. The recommended settings (as of ) are to follow the ne120 tunings for v0.3 listed in ne120 user_nl_cam. The user should change zmconv_tau from 3000 to 3600, an ne30 setting, when running RRM.
- Run your $CASENAME
- Report the machine upon which you successfully ran the RRM configuration. (/wiki/spaces/ED/pages/1867951 for a list of machines)
