Can ELMO be enabled in MPAS-CMAQ？

MPAS-CMAQ

Hello, everyone.

I’m attempting to simulate the SOA concentration and AOD550 using MPAS-CMAQ. I found that the default version sets L_ELMO =.false in ELMO_PROC.F, so the ELMO file is not output. I want to know if the current version supports L_ELMO =.true. If it is not supported, then is there any way to output the SOA concentration and AOD550? I would be very grateful for any reply.

ELMO does not work with the public release of MPAS-CMAQ, and development of the system is not currently an agency priority. If you want a variable from the phot module there are some hooks already in there for writing to the CTM_OUT file:

You can use that as a template to get whatever variables. Just remember to modify the file_input_c2_bdsnp.txt registry.
