中文摘要: 开展气球携带探空仪上升和降落伞携带探空仪下降的探空仪观测试验,建立针对下投式的温度、湿度和气压试验评估方法。试验结果表明上升段的北斗温度、气压测量准确度与RS92基本相当,湿度差于RS92双加热湿度传感器;下降段的北斗温度测量准确度与下降段的RS92基本相当,气压由于快速下降对定位有一定影响从而导致气压误差较大,相对湿度误差基本上在5%以内,符合WMO的测量要求;与风廓线雷达进行时空匹配,上升段北斗风向测量准确度差于RS92,风速测量准确度明显优于RS92。试验同时还验证了气球携带探空仪上升和降落伞携带探空仪下降全程2次探空观测模式具有很好的应用前景,可以实现高空站网的时空加密。

Abstract:The observation experiments of balloon borne radiosonde rising and parachute carrying radiosonde descending were carried out, and the methods for evaluating the temperature, relative humidity and pressure of dropsonde were established. The results showed that the accuracy of temperature and pressure of Beidou dropsonde ascending is quite similar to that of RS92, and the relative humidity is worse than the double heating humidity sensor of RS92. The accuracy of temperature of Beidou dropsonde descending is almost equivalent to that of RS92 and the pressure has some influences on the positioning due to the fast falling, resulting in greater pressure error. The error of relative humidity is basically within 5%, meeting the requirements of WMO measurements. Beidou and RS92 are matched with wind profile radar in time and space. On the rising phase, the accuracy of wind direction of Beidou is worse than that of RS92, and the accuracy of wind speed is significantly greater than that of RS92. In addition, the results showed that the 2-time observation mode of the ball-loaded descent sounding has good application prospect and could realize the densifying observation in space and time of upper-air station network.
