Regional 3.9 micron Infrared Satellite

This regional satellite map depicts radiative emissions at a particular wavelength (3.9 microns) in the infrared spectrum that is very useful for detecting wildland fires (wildfires or prescribed fires). Fires appear as distinct gray to black areas (often dots) against the usual light gray background. Clouds are depicted in whites and will usually obscure any surface fires. The time of the image is shown in UTC time at the upper left of the image (CST = UTC - 6 hours; CDT = UTC - 5 hours) and the map is typically updated every 15 minutes.
