CMAQv5.4, the latest version of the Community Multiscale Air Quality modeling system (release date October 14 2022), includes many new scientific and use-oriented features:

  • Updated chemistry for ozone (O3) and particulate matter (PM) formation from global-to-local scales
  • Introduction of the Community Regional Atmospheric Chemistry Multiphase Model (CRACMM)
  • Biogenic emissions algorithm options have been expanded
  • Revised algorithms for modeling the dry deposition of particles from the atmosphere (M3DRY and STAGE updates)
  • Streamlined building of the coupled WRF-CMAQ system compatible with WRFv4.4+
  • Improved efficiency, accuracy, and user experience for CMAQ instrumented model extensions CMAQ-DDM-3D and CMAQ-ISAM
  • Expansion of emissions diagnostic output features
  • Introduction of a domain-wide Budget Reporting tool
  • Online integration of common pollutant post-processing tasks (i.e. output total PM2.5 mass and more directly!)
  • Community Contribution: Incorporation of the Two-Dimensional Volatility Bases Set (2D-VBS) chemical mechanism
