摘要:

利用CSAT3三维超声风速仪与WXT520多功能气象传感器组成近地层光学湍流自动观测系统,使用太阳能电池供电和无线传输实现无人值守,可同时测量常规气象参数和大气折射率结构常数Cn2。系统包含一个控制中心和三个测量子站,可同时对三个测量点进行观测。通过对超声虚温进行湿度修正后得到真实温度,采用单点温度脉动法计算大气折射率结构常数Cn2,计算结果与温度脉动仪实测Cn2吻合较好。本系统可适应复杂恶劣的测量环境,性能稳定可靠,且测量子站可扩展。

Abstract:

The automatic observation system of the near surface optical turbulence is composed with CSAT3 three-dimensional sonic anemometer and WXT520 multifunctional weather sensor. Solar power and wireless transmission are used to realize unattended operation, while the conventional meteorological parameters and atmospheric refractive index structure constant Cn2 can be measured simultaneously. It consists of a control center and three sub stations, which can be measured at the same time to three points. The real temperature is obtained from virtual temperature via humidity correction. The atmospheric refractive index structure parameter Cn2 is calculated by using the method of single point temperature fluctuation, and the calculated results are in good agreement with the experimental results. The system can adapt to the complex and harsh environment, the performance is stable and reliable, and the sub station can be extended.

Key words: atmospheric optics, refractive index structure parameter, three-dimensional sonic anemometer, humidity correction
