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.
