Browse the various ozone garden locations by using the map below. You can click on a leaf for more information and to view the data collected at that location.

For comments or questions about this project, please email the garden leads team.

While looking at the data graphs think of:

  • When is ozone damage most severe? Ozone damage accumulates over time will likely become worse throughout the growing season.
  • Do you see high ozone concentrations? Ozone concentrations typically peak during the afternoon and are considered unhealthy by the EPA above 70 ppb.
  • Do you see a connection between ozone concentrations and plant damage? Continual exposure to high daytime ozone concentrations (typically above 40 ppb) will contribute to visible damage on plant leaves.
  • Note: We cannot guarantee accuracy as AirNow data comes from several government agencies.
  • Ozone affects plants over long periods of time.
  • Try to look at long term changes instead of daily fluctuations.
