Because there is no practical method to validate the precision of atmospheric transmittance for earth based infrared optical system measuring flying aircraft, this paper applies multiple linear regression to analyze the measured meteorological parameters and atmospheric transmittance, and points out that: 1) the effects of air pressure and visibility on atmospheric transmittance are contrary with physical laws; 2) among all the meteorological parameters, the angle of elevation has the greatest impact on atmospheric transmittance. By comparing with practical result of the experiment, it is found there is big difference. At last, conclusion is drawn that the accuracy of atmospheric transmittance provided by one infrared optical system is not high.
