中文摘要: 文章从静态指标与动态对比两个方面,对中国国产GTS1探空仪与芬兰Vaisala公司RS92探空 仪的综合性能进行对比。对比结果表明,GTS1探空仪温度存在滞后误差,RS92探空仪湿度测 量结果明显好于GTS1探空仪,200hPa以上RS92探空仪气压变化低于GTS1探空仪,测风精度方 面RS92探空仪高于GTS1探空仪,850hPa以下和150hPa以上GTS1探空仪测风与RS92探空仪存在 1m?s-1以内的系统差,RS92探空仪在整体性能上高于GTS1探空仪。

Abstract:The analysis and comparison are carried out between GTS1 radiosonde an d RS92 radiosonde from both static performance indices and dynamic characteristi cs, and the results show that the time lag effect exists in the temperature meas urement of GTS1 radiosonde, and the RS92 radiosonde gets obviously better humidity measu rement eff ect and lower pressure measurement above 200hPa than the GTS1 radiosonde. Meanwh ile, the RS92 radi osonde owns a higher wind measurement precision and there exsit systematic erro rs a bout 1m/s when the GTS1 radiosonde is located below 850hPa and above 15 0hPa. On the whole, RS92 radiosonde owns better performance.
