Scientists zeroing in on where air pollution goes in winter
HAMPTON, Va. (AP) - A team of scientists is flying over some of the largest metropolitan areas on the East Coast to get a better idea of how far air pollution travels and how it transforms during the cold, dark days of winter.
Researchers have been conducting flights from NASA's Langley Research Center in Virginia since Feb. 1 to measure pollutants in the air from New York to Atlanta and as far west as Cincinnati. The flights will continue through mid-March.
The role that emissions play in creating unhealthy air during the summertime is well understood, but there's been little research about what happens to those same pollutants during the winter.
Scientists say less sunlight allows for pollutants to travel farther before reacting to create ozone. The research could create better air quality forecasts.
