Continental Effects of 2004 Alaskan Fires (WMS)

Wildfires started by lightning burned more than 80,000 acres in Alaska in June 2004. The effects of these fires can be seen across North America with the Total Ozone Mapping Spectrometer (TOMS) instrument on the Earth Probe spacecraft. TOMS detects the presence of UV-absorbing tropospheric aerosols across the globe.

This animation shows aerosol index over Alaska from June 21 through July 10, 2004. Each image pixel corresponds to an area 1 degree in longitude by 1.25 degrees in latitude.

    Gaps with missing data were interpolated. Each frame was smoothed spatially, and the eastern (before midnight) edge of each frame was smoothed with the western (after midnight) edge of the following day's frame. The area of interest was extracted, expanded and smoothed. Low aerosol values (index less than 1) were made transparent.
