How to DESID region option?

CMAQ
1

I already read CMAQ/CMAQ_UG_appendixB_emissions_control.md at main · USEPA/CMAQ · GitHub and DESID paper but CMAQ cannot import region in my script.
I treid to put ALL instead of NC for DESID as well.
I think GRID mask file normally does not have any time demension.

Hi kkkghs0828,

Thanks for inquiring and sorry that the documentation was not clear enough. In the “RegionsRegistry | RGN_NML” variable, please replace the current value of the File_Label field (ISAM_REGIONS) with US_STATE, which is the label, specified in the CMAQ runscript, of the GRIDMASK file that you are reading from. That should do it, but of course check back in if it doesn’t work.

Best wishes,
Ben

Oh! When I try to use the region file, I have to make the new region field and setenv.

Thank you!
