            "description": "To determine the density of green on a patch of land, researchers must observe the wavelengths of visible and near-infrared sunlight reflected by the plants. The pigment in plant leaves, chlorophyll, strongly absorbs visible light (from 0.4 um - 0.7 um). Vegetation strongly reflects near-infrared light (from 0.7 -1.0 um). The more healthy leaves a plant has, the more the the visible light will be absorbed and the near-infrared will be reflected. In this animation, dark green indicates dense, healthy vegetation, whereas beige areas represent bare soil. Snow from the MODIS instruments is overlaid on top. || ",

            "description": "Records maintained by the National Interagency Fire Center (NIFC) and NASA both indicate that 2012 was an extraordinary year for wildfires in the United States.NIFC statistics show that more than 9.1 million acres had burned as of November 30, 2012—the third highest total in a record that dates back to 1960. Also notable: despite the high number of acres burned in 2012, the total number of fires—55,505—was low, the least on the NIFC record. Average fire size in 2012 was the highest on the record.The visualizations depict fires that burned between January 1 and October 31, 2012, as detected by the MODIS instruments. The fires are displayed over MODIS' vegetation and snow cover data. Yellow and orange indicates fires that were more intense and had a larger area of active burning. Most of these intense fires occurred in the western United States, where lightning and human activity often sparks blazes that firefighters cannot contain. Many of the lower intensity fires shown in red were prescribed fires, lit for either agricultural or ecosystem management purposes.The Terra and Aqua Moderate Resolution Imaging Spectrometer (MODIS) can routinely detect both flaming and smoldering fires that are aproximately 1000 square meters in size. Under pristine and extremely rare observing conditions even smaller flaming fires that are aproximately 50 square meters can be detected. Each active fire location represents the center of a 1 km pixel that is flagged by the algorithm as containing a fire within the pixel. For more information on the fire data, see the MODIS Collection 5 Active Fire Product User's Guide. For more information on the algorithm, see Giglio, L., J. Descloitres, C. O. Justice, and Y. J. Kaufman. 2003. An enhanced contextual fire detection algorithm for MODIS. Remote Sensing of Environment, 87:273-282 || ",

            "description": "For more than a decade, instruments on Terra and Aqua, two of NASA's flagship Earth-observing satellites, have scanned the surface of our planet for fires four times a day. The instruments, both Moderate Resolution Imaging Spectroradiometers (MODIS), have revolutionized what scientists know about fire's role in land cover change, ecosystem processes, and the global carbon cycle by allowing researchers to map the characteristics and global distribution of fires in remarkable detail. The collection of videos below provides perspective on how global fires impact humans and our planet. || ",

            "description": "This visualization leads viewers on a narrated global tour of fire detections beginning in July 2002 and ending July 2011. The visualization also includes vegetation and snow cover data to show how fires respond to seasonal changes. The tour begins in Australia in 2002 by showing a network of massive grassland fires spreading across interior Australia as well as the greener Eucalyptus forests in the northern and eastern part of the continent. The tour then shifts to Asia where large numbers of agricultural fires are visible first in China in June 2004, then across a huge swath of Europe and western Russia in August, and then across India and Southeast Asia through the early part of 2005. It moves next to Africa, the continent that has more abundant burning than any other. MODIS observations have shown that some 70 percent of the world's fires occur in Africa alone. In what's a fairly average burning season, the visualization shows a huge outbreak of savanna fires during the dry season in Central Africa in July, August, and September of 2006, driven mainly by agricultural activities but also by the fact that the region experiences more lightning than anywhere else in the world. The tour shifts next to South America where a steady flickering of fire is visible across much of the Amazon rainforest with peaks of activity in September and November of 2009. Almost all of the fires in the Amazon are the direct result of human activity, including slash-and-burn agriculture, because the high moisture levels in the region prevent inhibit natural fires from occurring. It concludes in North America, a region where fires are comparatively rare. North American fires make up just 2 percent of the world's burned area each year. The fires that receive the most attention in the United States, the uncontrolled forest fires in the West, are less visible than the wave of agricultural fires prominent in the Southeast and along the Mississippi River Valley, but some of the large wildfires that struck Texas earlier this spring are visible.
