The RRM branch has been merged to the ACME master.  Please see the updated 'how-to' document:   How to run the regionally refined model (RRM)

Please follow the steps below when wanting to run the regionally refined model (RRM) CONUS grid in ACME.

Step-by-step guide

Check-out the ACME's RRM branch:

1. Checkout the tangq/cam/RRM branch - see Development Quick Start for details

Create and build a new case from the scripts directory:

1. Suggested syntax:
   $ ./create_newcase -case $CASENAME -compset FC5 -mach (your-machine-name-here) -res conusx4v1_conusx4v1
2. Edit env_mach_pes.xml as needed.  For Redsky, using 200 cores and 1 thread for each component runs at 0.25 simulated years per day.
3. Edit env_run.xml as needed to specify the run-length. 
   
   1. set EPS_AAREA equal to 9.0e-06
      (or else you might see the error: "incompatible domain grid coordinate")
4. 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 /wiki/spaces/WORKFLOW/pages/7998629.)
5. Edit the namelist files (i.e., user_nl_cam) for user-specified output settings. 
6. Run your $CASENAME!
