Emissions Processing Training and Technical Assistance

The report summarizes the trainings provided for different sectors of emissions processing for photochemical modeling with the Emissions Processing Software version 3 (EPS3).

Develop CB7 Chemical Mechanism for CAMx Ozone Modeling

In this project, Ramboll updated the CAMx Carbon Bond (CB) chemical mechanism from CB6 revision 5 (CB6r5) to CB7 to provide the most up-to-date representation of atmospheric chemistry and reduce uncertainty in modeled ozone concentrations. The CB7 mechanism was tested and compared with CB6r5. (June 2021)
