This true-color satellite image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Aqua satellite on August 13, 2014 as it flew over Algeria. Dozens of wildfires burned though pine and oak forests in northern Algeria, primarily in the Tell Atlas mountain range.
Actively burning areas, detected by MODISís 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 in this image, such hot spots are diagnostic for fire.
