I am confusing about the treatment of black carbon in CMAQ simulation. As far as I know from Hu et al.,(https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2009JD011987), the Elemental carbon (EC) in the CMAQ model is black carbon, am I right?
If it is, may I ask what is the corresponding variable of black carbon in emission file under the CB6r3 mechanism? Can I just use the PM25_EC in the combined CCTM out file to represent black carbon in PM2.5?
Within the photolysis module in CMAQ, we believe EC is assigned optical parameters associated with BC.
Thank you! I’ve been looking for this for a long time…
