摘要
2012年8月,中国气象局气象探测中心在广东阳江开展自动探空系统新型GPS探空仪比对试验,对比分析其技术改进后的准确性,试验结果表明:温度测量性明显优于GTS1-2型探空仪。湿度测量结果与RS92型探空仪一致性较好,系统误差在15%RH内,标准偏差在12%RH内。气压系统误差全量程在±1.0hPa内,标准偏差在0.8hPa内。位势高度系统误差在±20gpm以内,标准偏差在70gpm内。GPS定位测风性能优于GTS1-2型探空仪配合L波段二次测风雷达测风性能结果。
In August 2012,an experiment was carried out on the new GPS radiosonde sounding system,an automatic sounding system,and the accuracy after its technology improvement is compared and analyzed.The results show that the temperature of new GPS radiosondes is significantly better than that of GTS1-2 radiosondes.The humidity results are consistent with those from RS92 radiosondes.The system error is 15%;the standard deviation is less than 12%.The system error of pressure is within ± 1.0hPa;the standard deviation is less than 0.8hPa.The system error of geopotential height is within ± 20gpm;the standard deviation is less than 70 gpm.The results of wind measurement are better than those of GTS1-2A.
