These images represent fire indications composited March 6 13, 2007, an 8-day period during which the southern U.S. was subjected to numerous prescribed burns. This image is the entire tile h10v05, including most noticeably the Mississippi River, and portions of the surrounding southern States. Below is a zoomed view along the Gulf of Mexico showing proliferate fire activity throughout Mississippi, Alabama, and Florida.
Using the MOD14A2 Fire Mask a color code was applied to highlight fires in yellow, water bodies in blue, and leaving land area in black. Each yellow pixel is 1km2.
MODIS Thermal Anomalies/Fire products are primarily derived from MODIS 4- and 11-micrometer radiances. The fire detection strategy is based on absolute detection of a fire (when the fire strength is sufficient to detect), and on detection relative to its background (to account for variability of the surface temperature and reflection by sunlight). Numerous tests are employed to reject typical false alarm sources like sun glint or an unmasked coastline.
MOD14A2 data are 8-day fire-mask composites at 1-kilometer resolution provided as a gridded level-3 product in the Sinusoidal projection. Science Data Sets include the fire-mask and algorithm quality.
The Terra MODIS instrument acquires data twice daily (10:30 AM and PM), as does the Aqua MODIS (1:30 PM and AM). These four daily MODIS fire observations serve to advance global monitoring of the fire process and its effects on ecosystems, the atmosphere, and climate.
Version-5 MODIS Thermal Anomalies & Fire products have attained Validation Stage 3, which was completed using active fire reference data that were derived from ASTER and Landsat-5 TM (30 m resolution) data sources.
