Abstract
Spectrum for smoke absorption factor over the range of 0.28 ÷ 6.5 microns is presented. Measurements were carried out in the model local forest fire at natural convection without a wind. Absorption lines of water vapor (bands of I .8 and 2.7 microns) and carbonic gas (band of 4.3 microns) were identified in the spectrum. It was shown, that the concentration in smokes at the rear of fire front increased by a factor of 1 .5 ÷ 2 for water vapor, and up by a factor of 3 for carbonic gas in comparison with initial concentration in the clean medium.
