Hi Support Team,

I notice that in the OFFLINE_BIOGENICVOC section of HEMCO_Config.rc, there are SOAS emission scaled from precursors:

Have two questions: (1) I thought the formation of SOAS should be 100% during chemistry, why we put it into the HEMCO emission module? Feel free to correct me if my understanding is wrong. (2) Why the scaling factors for SOAP & SOAS are the same?

Thanks, Yanshun
