Intense fires in eastern Alaska and Canada’s Yukon Territory are spreading smoke across much of northern Canada. These image, taken by NASA’s Total Ozone Mapping Spectrometer (TOMS) on June 25-27, 2004, show the progression of the smoke east over three days. TOMS measures the relative amount of solid or liquid particles, aerosols, suspended in the atmosphere. Here, red pixels show the high aerosol concentrations associated with smoke. Lighter aerosol concentrations are represented by yellow and green.
