Satellite instruments detect fires using mid-infrared bands where fires typical emit strongly. Fire products may use data from polar orbiting instruments, geostationary instruments or a combination of both. The advantage of the polar orbiting instruments is their high resolution which allows them to detect smaller and/or less energetic fires than the geostationary instruments. The geostationary instruments have much higher temporal coverage and may observe many fires that the polar orbiting instruments will not see since the overpass is not coincident in time with the fire.
Fire products may rely solely on automated algorithms for fire identification or may supplement procedure with human analysis to remove suspected false positives or to add hotspots.
MODIS can typically detect flaming and smoldering fires 1000 m2 in size but depending on conditions and fire type may detect fires as small as 50 m2. For additional information on fire products from MODIS, including a more complete discussion of minimum fire size detected and factors effecting fire detection please see the excellent LANCE FAQ from NASA’s EOSDIS and scroll down to the “FIRMS” section.
