With the end of September comes the end of smog season in metro Atlanta, which has seen worse years for air pollution. As cooler temperatures arrive to clear the skies, air quality experts say pollution controls combined with good weather gave the area one of its easiest-breathing summers in a decade.

Michael Chang, an atmospheric scientist at Georgia Tech, says there has been “some measurable progress.”

This was the third-best year for air quality since 1998, when Georgia began measuring eight-hour periods of ground-level ozone, a key component of smog.

But the standard is rising. The Environmental Protection Agency has new limits on ground-level ozone of 75 parts per billion over eight hours, down from 84 parts per billion.
