摘要
用AMK-02型超声波大气参数综合测量仪同时测量了常规气象参数和大气折射率结构常数Cn2,分析并找出了该仪器给出的Cn2在转换时刻与热丝温度脉动仪的测量结果差异较大的原因,是由于超声波法测量温度脉动精度太低,只能达到0.01K.同时建立了另一种适用于超声波仪计算Cn2的方法,即利用该仪器准确的常规气象参数计算Cn2,其计算结果与热丝温度脉动仪的测量结果吻合较好.
Abstract
The AMK—02 ultrasonic measurement meter can measure meteorological and turbulent parameters of the atmosphere.The temperature pulsation sensitivity of the AMK—02 is too low to calculate the refractive-index-structure parameter Cn2 accurately at the time of sunrise and sunset.The calibrated meteorological parameters are used to calculate the refractive-index-structure parameter Cn2 accurately,and the calculated results accord well with that of the hot wire anemometer.
