South of the snow line in eastern Russia, numerous fires were burning and filling the skies with thick smoke on April 23, 2003. This Moderate Resolution Imaging Spectroradiometer (MODIS) from the Aqua satellite shows the fires marked with red dots in Russia (top) and China (bottom). Dark brown burn scars are associated with many of the fires, and the smoke covers thousands of square kilometers.
