What is the relationship between light-absorbing aerosols and AAOD in WRF-CMAQ

Hi all,

I would like to know the relationship between AAOD changes and Black carbon. I want to separate the effects of BC, Dust, EC to AAOD. As a result , i want to know the Parameterized scheme of AAOD in RRTM. I have read Atmospheric and Environmental Research R&C. But i didn’t find it.

I would like to know which factor effects AAOD in WRF-CMAQ, how can they effect AAOD and which file controls the input of species information from the CMAQ model to the WRF model.
