The MODIS instrument onboard the Terra and Aqua satellite, was specifically designed to detect fires.

Burning carbon particles both on the tiny soot particles in the flame and on the fuel itself emit a very specific wavelength of light, 3.8 to 4 microns. NASA research has contributed to much improved detection of fire for scientific purposes using satellite remote sensing and geographic information systems. This has helped advance our understanding of the impacts of fire in many areas of earth science, including atmospheric chemistry and the impacts on protected areas.

Collectively, these fires account for 70 percent of the total area burned by fire around the world. Humans set the majority of fires in Africa, burning land for farming and pastoral grazing. The practice is widespread and accepted by Africa's fire management community. Fire clears excess vegetation, creates new areas for cultivation and returns nutrients to the soils. Lightning fires, though not entirely uncommon, contribute much less to the total burning across the African landscape. At the beginning of the wet season, dry vegetation can readily ignite when struck by lightning. Such spontaneous ignitions can lead to wildfires that burn for days. The visualization below shows nearly a decade of fire observations throughout Africa collected by NASA satellites from July 2002 through July 2011. Watch how as the seasons shift from wet to dry, waves of fire sweep across the continent from the semi-arid grasslands and savannas just below the Sahara Desert in the north, to the equatorial forests in central Africa and lush landscapes of the south. || ", "release_date": "2011-11-03T00:00:00-04:00", "update_date": "2023-05-03T13:53:30.248882-04:00", "main_image": { "id": 481429, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a010800/a010832/3870_africaNDVI_1024x576.4050.jpg", "filename": "3870_africaNDVI_1024x576.4050.jpg", "media_type": "Image", "alt_text": "Find out how Africa's numerous fires ignite.", "width": 1024, "height": 576, "pixels": 589824 } } ], "sources": [], "products": [], "newer_versions": [], "older_versions": [], "alternate_versions": [] }
