Forest fires (marked with red dots) surround southern Russia’s Lake Baikal on June 9, 2003. Scores of fires are burning in a variety of ecosystems, including mature spruce forests, cedar forests, and mixed forests. Smoke from these fires has been streaming across eastern Russia and China and out over the Pacific Ocean off and on for months, and has traveled around the world, reaching Canada and the United States. This true-color image was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite.
