Notice: Because the primary pollutant for the Dallas-Fort Worth region is ozone,
we have chosen to display specific charts, data, and images reflective of this pollutant’s measured concentrations; therefore, the numbers above correspond specifically with ozone concentrations. Ozone levels are mapped to colors based
on a EPA's projected eight-hour average calculated from the measured one-hour levels.
