Intense fires continued to burn in the boreal forests of eastern Siberia on August 1, 2010. The fires are outlined in red in this image, acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite. The fires span the borders of Russia’s Chukotskiy, Magadan, and Koryakskiy provinces.
Burning in coniferous (evergreen) forests, the fires blanketed northeastern Siberia with thick brown smoke. The smoke hugs the ground near the fires, filling valleys, and soars over clouds farther away from the flames. On August 1, the smoke flowed north from the fires and over the Arctic Ocean. A wide view of the Arctic shows the smoke crossing the Bering Strait and clouding skies over northern Alaska.
