This true-color satellite image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Terra satellite on July 13, 2015 over eastern Asia. Most hot spots are in eastern Russia (north and west of the black border lines) with few spots found in China. Actively burning areas, detected by MODIS’s thermal bands, are outlined in red.

Each hot spot, which appears as a red mark, is an area where the thermal detectors on the MODIS instrument recognized temperatures higher than background. When accompanied by plumes of smoke, as those seen drifting southward in this image, such hot spots are diagnostic for fire. The smoke released by any type of fire (forest, brush, crop, structure, tires, waste or wood burning) is a mixture of particles and chemicals produced by incomplete burning of carbon-containing materials. All smoke contains carbon monoxide, carbon dioxide and particulate matter or soot.
