NASA measures wildfire pollution pour over Niagara Falls

s and coal-burning power plants is sulfur dioxide (SO2).

Between July 18 and 20, the greatest pollution, or quantity of aerosols were north of the Great Lakes. Over a large area stretching from the north of western Lake Superior east to Lake Huron, particles measured highest at 1.5 molecules per cubic centimeter.

Giovanni is a Web-based application that provides a simple and intuitive way to visualize, analyze, and access vast amounts of Earth science remote sensing data without having to download the data.

"One of the advantages of Giovanni is that it allows us to make rapid multi-day averages of daily data from MODIS," said Dr. James Acker, an oceanographer at the Goddard Earth Sciences Data and Information Services Center (GES DISC) who is creating a Giovanni data portal specifically for educators. GES DISC operates out of NASA's Goddard Space Flight Center in Greenbelt, Md. "By averaging the data, we can see the full extent of smoke from the fires, which can be a health hazard," Acker said. "The AOD data also clearly indicates where the smoke is, and distinguishes it from weather clouds."

Dr. Acker recently experienced wildfire smoke first-hand at a teacher workshop in northeastern New Mexico, where the air quality was noticeably affected by the huge Wallow Fire in Arizona, nearly 300 miles away.
