2. Change grid resolution

2. Change grid resolution
arbetter Fri, 10/23/2020 - 15:39

There are 4 global resolutions supported by the UFS Medium Range Weather App.  For this training session, please use only the C96 or C192, due to computational (and classtime) limits.  The model resolution is specified with the “--res” option to the create_newcase command.

Starting at Step #3 from the Day 1 exercises, select a different resolution.  You can query available grid resolutions by:

cd $HOME/UFS_training/my_ufs_sandbox/cime/scripts
./query_config --grids
     alias: C96
       non-default grids are: atm:C96

     alias: C192
       non-default grids are: atm:C192

     alias: C384
       non-default grids are: atm:C384

     alias: C768
       non-default grids are: atm:C768

Select a C192 grid, and create the new case directory:

./create_newcase --compset GFSv15p2 --res C192 --case $UFS_SCRATCH/ufs-mrweather-app-workflow.c192 --workflow ufs-mrweather
cd $UFS_SCRATCH/ufs-mrweather-app-workflow.c192

Then, continue with the instructions for Steps #4-7 from Day 1.
