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

  • Date
  • Federal Information Processing Standard (FIPS) Code
  • Latitude of US Census Tract Centroid
  • Longitude of US Census Tract Centroid
  • Pollutant Prediction [either PM2.5 (ug/m3) or O3 (ppb)]
  • Standard Error of Prediction
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.
