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.

Color Air Quality Rating 1-Hour
Average
(µg/m³)		 24-Hour
Average
(µg/m³)		 Actions to take
Moderate 15.5 - 35.4 12.1 - 35.4
  • No health impacts are expected when levels are within this range.
  • No special actions are required when levels are within this range.

PLEASE NOTE: This data has not been verified by the IDEM and may change. This is the most current data, but it is not official until it has been certified by our technical staff. Data is collected from IDEM ambient monitoring sites and may include data collected by other outside agencies. This data is updated hourly.
