For 1999 and after, click on the date for the corresponding eight-hour average peak ozone map for that day.
In October 2015, EPA revised the 8-hour ozone standard and changed the Air Quality Index (AQI) to align with this new standard. Maps for days in 2007 and earlier are based on the 1997 8-hour ozone standard (0.08 ppm). Maps for 2008 through 2015 are based on the 2008 ozone standard (0.075 ppm). Maps for 2016 through 2022 are based on the 2015 ozone standard (0.070 ppm). Click Here for a table showing the revised AQI breakpoints for the 1997, 2008, and 2015 ozone standards.
