Recent Advances in CAMx Air Quality Modelling
Ozone Source Apportionment Technology (OSAT) and its derivatives to identify the contributions of source regions and emission categories to ozone.
Decoupled Direct Method (DDM) sensitivity analysis approach to estimate the sensitivity of ozone and other pollution concentrations to key input parameters including emissions, initial concentrations, and boundary conditions.
Process Analysis (PA) to explain the processes that lead to and govern ozone formation using the integrated process rate (IPR) and integrated reaction rate (IRR) and Chemical Process Analysis (CPA) methods.
Particulate Matter (PM) implementation to treat size resolved PM using a sectional approach and state-of-science aerosol thermodynamic, aqueous-phase chemistry, mass transfer, and deposition algorithms; and
Extension to treat air toxics that includes a subgrid-scale Gaussian puff model to estimate the maximum near-source concentrations from air toxic point sources.
