To guide development of coupled atmosphere-fire models, a suite of instruments was assembled to examine the dynamics of wildfires. Visible and Infrared (IR) imaging and UV through near IR spectral observations were made of the Frostfire prescribed burn carried out 8-10 July 1999 at the Caribou-Poker Creeks Research Watershed (CPCRW) near Fairbanks, Alaska. Five video cameras were utilized. A color camera was used to record normal sight visible images. A black and white camera with broad spectral sensitivity in the UV and visible was used with a filter centered on 510 nm to assess the possibility of observing a strong C2 visible emission band as a method to increase the contrast of flame structures. One infrared camera viewed from the ground and one from the air; these were used to record images in various IR spectral bands. A second airborne visible video camera was used to identify the targets of the airborne video IR measurements. In addition to the cameras, a dual grating spectrometer was used to record emission spectra from 200-1100 nm and a visible-IR cross track line scanners was used in the aircraft.
