NASA Video Shows Global Reach Of Pollution From Fires


The concentration and global transport of carbon monoxide pollution from fires burning in Russia, Siberia and Canada is depicted in two NASA animations created with data from the Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua spacecraft.

by Staff Writers Pasadena CA (JPL) Aug 13, 2010 Two movies were created using continuously updated data from the "Eyes on the Earth 3-D" feature on NASA's global climate change website They show three-day running averages of daily measurements of carbon monoxide present at an altitude of 5.5 kilometers (18,000) feet, along with its global transport. The data are from the Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua spacecraft. AIRS is most sensitive to carbon monoxide at this altitude, which is a region conducive to long-range transport of the smoke.
The abundance of carbon monoxide is shown in parts per billion, with the highest concentrations shown in yellows and reds.
The first movie, centered over Moscow, highlights the series of wildfires that continue to burn across Russia. It covers the period between July 18 and Aug. 10, 2010.
The second movie is centered over the North Pole and covers the period from July 16 to Aug. 10, 2010. From this vantage point, the long-range transport of pollutants is more easily visible.
