Fire Detection (3 of 5)

The three pixels pointed to by the arrow in this 3.9 um image are those being directly affected by the Pingree fire at 9:00 PM LST (time of map, previous page). The GOES is viewing an unobscured fire scene. At this time, the only clouds in the region were a scattered, thin cirrus deck not over the fire scene (fires can be observed through thin cirrus at 3.9 um). VIS imagery showed smoke from the fire was advected eastward, and with the satellite viewing from nearly due south, smoke obscuration was minimal. Finally, a significant part of the hottest burn was in the crowns of the trees, eliminating the possibility of tree canopy obscuration of a brush fire below, allowing the GOES a nearly unobscured view of the fire scene.

The 3 rows of numbers show the temperatures (K) of the pixels in the immediate proximity of the fire, including the three fire-affected pixels (asterisked).
