摘要: 最新研制的湍流气象探空仪是将温度脉动仪附加在常规气象探空仪上，实现了两路折射率结构常数、温湿压常规气象参数、温度谱等测量。通过在合肥和长春的实验表明该系统具有较高的测量精度和稳定性，在高空低温动态条件下探空仪系统噪声与温度脉动仪地面常温静态条件下的噪声相当。探空系统噪声引起的等效折射率结构常数小于2×10-18 m-2/3。能服务于激光传输、大气质量评价及天文台选址等相关领域对大气光学湍流研究的需要。Abstract: A new meteorologic radiosonde for turbulence was introduced, which coupled a microthermal sensor to a conventional meteorologic radiosonde. It could obtain two-way refractive index structure parameter, general meteorologic parameters (temperature, humidity and pressure), temperature spectrum etc. synchronously. Experiments of results in Hefei and Changchun indicate the system can achieve high precision and stability. The system noise detected in the dynamic circumstance of high altitude low temperature corresponds with that in static state normal temperature on the ground. The equivalent refractive index structure parameter resulted from the system noise in dynamic state is less than 2×10-18 m-2/3. This radiosonde can meet the need of atmospheric optical turbulence
