Ozone (O3) and Fine Particulate (PM2.5) Surfaces

  • Date
  • Longitude
  • Latitude
  • CMAQ Column
  • CMAQ Row
  • Prediction of Average Pollutant Concentration for the CMAQ grid cell - either PM2.5_pred (ug/m3) or O3_pred (ppb)
  • Standard Error of Prediction - either PM2.5_stdd or O3_std

The National Center for Environmental Health provided resources to help support the development of the O3 and PM2.5 predictive surfaces through its Environmental Public Health Tracking system.
