Air Quality

The AirData Air Quality Monitors application displays EPA outdoor air quality monitor locations and monitor-specific information. It also allows the querying and downloading of data daily and annual summary data. Data includes monitoring data and emissions data. Monitoring sites report data to the EPA for six criteria pollutants:

  • Ozone (O3)
  • Particulate matter (PM10 and PM2.5)
  • Carbon monoxide (CO)
  • Nitrogen dioxide (NO2
  • Sulfur dioxide (SO2)
  • Lead (Pb)

To use the map select a layer to display using the layer list icon in the upper right. If multiple layers are selected you can show a legend using the legend icon in the upper right. A marker will appear on the map for each station in the selected layers, which can be clicked on to bring up specific data for that station along with daily and annual data download links.
