AQI Calculations on 09/26/2026 1:00AM - 7:00AM

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.


Due to limited system resources and high volume, today's AQI calculations can no longer be sorted by columns. For a CSV file of these data, updated hourly, click here.


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