AIR QUALITY MODEL (AQM)
COMMUNITY MULTISCALE AIR QUALITY (CMAQ) MODEL

The Operational NOAA-EPA National Air Quality Forecast Capability (NAQFC) ozone and fine particulate matter (PM2.5) predictions are produced twice daily to 48 forecast hours for the 06 and 12 UTC run cycles. The system consists of the Community Multiscale Air Quality (CMAQ) model, which is driven by the NWS North American 12-km meteorological (NAM) model. The operational CMAQ v5.0.2 running at NCEP uses CB05 chemical mechanism, the AERO-5 aerosol chemistry, latest point sources emissions, EPA National Emissions Inventory 2014v2 area and mobile sources and Biogenic Emissions Inventory System that uses the Biomass Emission Land Database v3. Aerosol lateral boundary conditions are provided by the NWS GEFS-Aerosol global 4x/day predictions. Bias corrected ozone and PM2.5 predictions are also produced using the ESRL analog Kalman Filter method.
