Historically there have been three definitions of Air Quality Index ranges (the breakpoints that define color codes). For all dates before 12 March 2008, we use the "1997 breakpoints" for displaying colors. For dates between 12 March 2008 and 27 December 2015, we use the "2008 breakpoints." View the color code breakpoints.

The data reported from Buncombe County are collected by the Western North Carolina Air Quality Agency.
The data reported from Mecklenburg County are collected by Mecklenburg County Air Quality.
