Key to Ozone Highlight Colors:

Hourly ozone levels have been mapped to a set of surrogate values based on custom 1-hour breakpoints.
The table below shows the levels, color-coding, and suggested actions for the 1-hour surrogate.

Ozone levels in this range are projected to be moderate based on the one-hour surrogate calculation for Ozone.
  • Unusually sensitive individuals may experience respiratory symptoms.
  • Unusually sensitive individuals may experience respiratory symptoms.
Ozone levels in this range are projected to be very unhealthy based on the one-hour surrogate calculation for Ozone.
  • Increasingly severe symptoms and impaired breathing likely in active children and adults and people with respiratory disease, such as asthma; increasing likelihood of respiratory effects in general population.
  • Increasingly severe symptoms and impaired breathing likely in active children and adults and people with respiratory disease, such as asthma; increasing likelihood of respiratory effects in general population.

Key to PM-2.5 (Local Conditions) Acceptable Highlight Colors:

The color-coding of the hourly PM-2.5 data is based on a 1-hour to 24-hour projection. This projection is based on statistics compiled over several years comparing the daily maximum 1-hour average to the midnight-to-midnight 24-hour average.
The table below shows the levels, color-coding, and suggested actions for both the 1-hour projection and the actual 24-hour standard.
