Some of those hazy days this past summer may have been due not just to too many cars or smokestack in Ohio.
It could have come from Asia.
Researchers at the University of New Hampshire have found plumes of air pollution from Asia over the East Coast this summer.
As NHPR's Mark Bevis reports
Robert Talbot is the Director of Climate Change Research at the University of New Hampshire.
He also leads the International Consortium for Atmospheric Research on Transport and Transportation.
It goes by the acronym ICARTT.
This summer, teams of Talbot's scientists have been working in aircraft tracking air masses and plumes of pollution.
He says researchers have known for some time that the Asian air pollution makes its way across the Pacific.
But now scientists can quantify it.
