Hi,
You only need to run ungrib.exe of WPS to produce the intermediate format datafiles, which are later used for generation of lateral boundary fata for regional MPAS run. You don't need to specify domain and run geogrid.exe.
Hi Ming,
That was helpful. Thank you so much.
I have a follow-up question.
I am trying to use 60-km – 3-km mesh for running limited area simulation. While interpolating initial regional conditions, I get the following error msg when I run the init_atmosphere_model program with 36 MPI tasks.

Could you please help me understand what I am doing wrong and what parameters I need to change?
Thank you.
