I encountered another issue related to the VOC species allocation. As we know that there are two types of VOC species in the SMOKE modeling process, the first one are model species such as ALD2, OLE, BENZ and ALDX while another one is the true species which measured in the atmosphere (such as Butenyne, 1-Butenyne and 2-methylbenzofuran etc. ). The question in my mind is that how could we allocate the initial VOC emission amount based on the NEI emission inventory to the detailed true VOC species rather than the model species. I have tried many tools like SPECIATE(https://www.epa.gov/air-emissions-modeling/speciate) and Speciation_Tool(https://www.cmascenter.org/help/documentation.cfm?MODEL=speciation_tool&VERSION=4.0). However, all these tools only give the final VOC species for CMAQ/CAMx model species.
To my knowledge, I think that there may be an option for generating the real VOC species rather model species in these models and tools but I don’t find it right now (Because I find that the SMOKE utilize the SPECIATE for dealing with the initial NEI emission inventory and give the final results of model species which we always use it for driving CMAQ).
For example, currently, I have the emission amount of each emission sector in Los Angeles (the data has attached in this email). To do the true VOC species allocation and calculate the true VOC emission amount in Los Angeles , I guess we should find the source emission profile to do the allocation. Does the source emission profile exist in the SMOKE model?
Thanks a lot for any help!
