Fires throughout Ontario are generating pollution that is showing up in data from NASA’s Aura Satellite in the Great Lakes region.
The fires have also forced thousands of residents to evacuate to other areas in Canada, according to CBC News. About 112 fires have ravaged 81,545 acres so far. Because of the smoke from wildfires blowing south, the Minnesota Pollution Control Agency issued an air pollution alert, according to the Duluth News Tribune.
An image of the pollution from fires in Ontario was created from data of nitrogen dioxide (NO2) levels over the period from July 15, 2011 to July 18, 2011. It was created from Ozone Measuring Instrument (OMI) data using the NASA Giovanni system. NO2 forms during fires when nitrogen reacts with oxygen. In fact, NO2 is formed in any combustion process where the oxygen is provided by Earth’s atmosphere.
Detection of NO2 is important because it reacts with sunlight to create low-level ozone or smog and poor air quality. The OMI instrument that flies aboard NASA’s Aura satellite is able to detect NO2. Low-level ozone (smog) is hazardous to the health of both plants and animals, and ozone in association with particulate matter causes respiratory problems in humans.
OMI measures NO2 by the number of molecules in a cubic centimeter. The highest concentrations appear in dark red and are located at the southern tip of Lake Michigan.
OMI data is archived at the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC), and is provided by KNMI, the Koninklijk Nederlands Meteorologisch Instituut (Royal Netherlands Meteorological Institute). (SpaceDaily)
