Abstract:

The atmospheric structure constant of refractive index Cn2 is an important parameter of denoting atmospheric turbulence. The atmospheric structure constant of refractive index Cn2 is measured both in noonday and at night in everyday at all seasons, respectively, using QHTP-2 micro-thermal meter. The vertical profile of Cn2 in Hefei(0~25 km)is investigated by analysis of experimental data, and the statistical matrix and statistics distribution is discussed in detail. It’s shown that variance profile of Cn2 in Hefei coincide with lognormal distribution, the probability distribution of Cn2 has conspicuous difference day and night.

Key words: applied optics, atmospheric turbulence, atmospheric structure constant of refractive index, variance profile, statistical matrix; probability
