AQI Calculations on 05/29/2017 1:00AM - 9:00AM

The EPA (Environmental Protection Agency) developed the AQI (Air Quality Index) to make reading ambient air data more understandable to the general public. When ambient air data is collected, the numbers are converted from their concentration levels into numbers on a scale. That scale is the pollutant's AQI value. (Click here for a more detailed description of the AQI scale). Below is a list of all of the latest AQI values collected.

Click on the column headings to sort data.

All data are collected real-time and have not been corrected nor validated.
