摘 要: 为给气象探测中日常使用的探空仪提供对比和校准,提出一种基于高精度温度测量电路和ARM 处理器的标准探空仪系统。该系统包括球载部分和地面部分,球载部分集成了阵列式探空温度传感器,且可以外接高精度露点仪、压力计等气象传感器。利用计算流体动力学(computational fluid dynamic,CFD)方法对阵列式温度传感器进行数值仿真,仿真结果显示该传感器可降低热污染误差。搭建一套高空环境模拟实验装置,实验结果表明,阵列式探空温度传感器与传统探空温度传感器相比,降低了横梁尾流在上升过程中对传感器探头的影响,与仿真结果吻合度较高。该标准探空仪系统与业务探空仪相比,具有温度测量精度高、噪声低、扩展能力强等优点。

Abstract: In order to provide comparison and calibration for the daily use of radiosonde meteorological observation, a reference radiosonde system based on a high-precision thermometer and an ARM processor is proposed. The system includes an airborne subsystem and a ground-based subsystem. The airborne subsystem includes an array-based sounding temperature sensor. A variety of meteorological sensors, such as dew point hygrometer and pressure sensor can be integrated. A computational fluid dynamic (CFD) method is utilized to simulate the array-based temperature sensor. Simulation results suggest that the new design helps to reduce the solar radiation error resulted from heat contamination. A low-air-pressure experiment platform is constructed to simulate high altitude environment. Experimental results indicate that this array-based sensor is able to reduce the error resulted from the heat contamination considerably, which agrees with the simulation results. The sensor also features relatively small radiation error, compared to traditional bead thermistor sounding temperature sensors. The reference radiosonde system, compared with the traditional radiosonde, features high precision of temperature observation, low noise and high extensibility.
