The complexity of the optical properties of atmosphere demonstrated in spatial and temporal characteristics causing
the effect of optical properties on laser engineering could not be determined simply. It is necessary to reproduce the
panorama of optical properties of atmosphere, and in this case the effect of optical properties on laser engineering could
be evaluated. The survey of optical properties of atmosphere is continuous; facing zillions of data that changed
instantaneously, the statistical method must be used while the original characteristic of optical properties of atmosphere
in spatial and temporal distribution should be restored. Measurements of laser beam propagation in the atmosphere are
taken. the wavelength is 0.946 μm and the transmission length is 2 kilometers. The data we achieved were made an
hourly average, and then the same parameter based on each hour were made a monthly average, in this sense each
parameter has 288 groups of data; the annual statistical characteristic value of different optical properties including
atmospheric temperature, humidity, wind speed, visibility and the refractive-index structure parameter C2N were
obtained. The molecular absorption, the aerosol particle scattering and extinction, the turbulence effects and the
comprehensive effect of light propagation in the atmosphere were analyzed and evaluated for the atmospheric conditions
in the whole year by using this method. The distribution and statistical characteristics of effects of atmosphere optical
properties on the propagation were carried out. Analysis results show that, thorough understanding of the atmospheric
optical properties in the application areas is very important to all kinds of laser engineering, including feasibility analysis
of laser engineering, optical system design and performance evaluation. And statistical analysis method is an effective
means to master the characteristics of complex system. It turns out that the effects of optical properties of atmosphere on
the laser engineering is complicated and various, and a statistical method for a study of the analysis of the complex
spatial and temporal distribution characteristics value is presented meanwhile.
