Comparison between atmospheric chemistry model and observations utilizing the RAQMS-CMAQ linkage

► Updated RAQMS-CMAQ linking tool by adding the CMAQ aerosol modules (AERO3 & AERO4). ► Included additional gas phase species from RAQMS to RAQMS-CMAQ. ► Investigated the impacts of the lateral boundary condition on CMAQ simulations. ► Characterized the model results by comparing with in-situ measurements at Moody Tower. ► Used the improved dynamic boundary conditions to discuss the improvement of ozone simulation.
