The aerosol optical thickness (AOT) and pyrogenic events variations in central Yakutia in 2000-2009 were researched
on remote sensed data (NOAA, Terra and Aqua). It is shown that summer average (June-August) of AOT
for years with high pyrogenic activity (2001-2003) is greater by ~ 125% than AOT of years with low pyrogenic activity
(2000, 2004-2009). In some days when forest fires were most strong the daily AOT in central Yakutia was up
to 1,5-1,6 strongly exceeding undisturbed values.
