October is better month for air quality

by Joseph Cress

Excerpt:

Carlisle-area residents can breathe a little easier knowing that, statistically, October tends to be the best month in terms of local air quality.

Autumn weather patterns produce conditions that lead to reduced concentrations of fine particulate matter in the air, a Shippensburg University professor has concluded.

Timothy Hawkins, an associate professor of geography and earth science, spoke on the relationship between weather and fine particulates at a Clean Air Board community meeting Thursday night. Particulate matter are particles of dust, dirt, soot, smoke and liquid droplets that can stay suspended in the air for long periods of time.
