Can ELMO be enabled in 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.
