Fire Detection (4 of 5)
During day-time, visible imagery can be used to infer fire locations from smoke
plumes. Smoke from larger fires is particularly easy to see in visible image
loops, appearing as light-colored, hazy plumes emanating from a small area.
Observe the smoke plumes produced by very large,
controlled burns near the cities of Pensicola and Apalachicola, FL (both, near
the Gulf coast) in the stll image below. Arrows are added to identify the positions
of the two larger Florida smoke plumes, as well as two smaller plumes, one in MS,
and the other in AL.

Smoke from smaller fires, including the two smaller plumes just mentioned, is
not always evident in VIS imagery. This will become apparent when the 3.9 um
imagery for this case is presented on the next "display page" (click on "Continue"
