On the operative method measuring of the atmosphere’s infrared transparency

The results on development of an original method of atmosphere’s transparency determination in the infrared region are presented. The method is a half-empirical and based on the direct nephelometric and meteorological measurements of the atmosphere’s transparency in the visual region (on $\lambda=0.55\mu m$) with following recalculation to the other spectrum region in diapason from $1$ to $14 \mu m$. The proposed method provides the possibility of the operative valuation "optical weather" in the atmosphere, especially in full-scale tests thermovision equipment and devices of night vision.
