Air quality reports use the Air Quality Index,
which represents the higher of two pollutants - PM2.5 or ozone. For
ground-level ozone (O3),
these values are based upon an 8-hour running average. For
ground-level particulate matter with a diameter less than 2.5
microns (PM2.5), these values
are based upon a 24-hour daily average.
