    N/A indicates data is not available.
    A blank space indicates the parameter is not measured at that monitoring site.

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 people should consider reducing prolonged or heavy outdoor exertion.

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.

  • No health impacts are expected when levels are within this range.
  • No special actions are required when levels are within this range.
