摘　　要：采用同球施放的方法,对芬兰维萨拉GPS探空仪的性能进行了试验。结果表明:气压和湿度的测量一致性符合RS92型GPS探空仪的探空整体非确定性的标称;温度除白天10 hPa外,其它各规定层都能够满足RS92型GPS探空仪的探空整体非确定性的标称;湿度、风速能够满足WMO对全球气候观测系统(GCOS)探空的要求,高度能很好满足WMO对GCOS探空的要求。辐射特性分析表明,RS92型GPS探空仪在70 hPa以下受辐射影响较小,20 hPa以上温度受辐射影响相对较大。出、入云特性分析表明,RS92型GPS探空仪的湿度测量性能较好,能较灵敏地跟踪湿度变化,温湿度配合合理,数据丢失情况比RS80型探空仪明显减少,但产品在稳定性、检测和软件方面仍需要改进。Through releasing three sets of radiosonde tied by a same balloon, the performance of the Finland Vaisala sounding system was tested. The results indicate that the consistency of pressure and humidity is in accordance with the technical specifications of RS92 GPS radiosonde, so is temperature except in the 10 hPa layer in the daytime; humidity and wind meet basically the requirements of WMO for the GCOS （Global Climate Observing System）; geo-potential height can well satisfy the WMO GCOS requirements. The analysis of the radiative characteristics shows that the influence of solar radiation is small below 70 hPa and great above 20 hPa. The experiment suggests that the radiosonde can also sensitively detect humidity with good measuring performance within clouds; the coordination between temperature and humidity is reasonable; the data losses of RS9GPS2 are significantly less than those of RS80, but improvements are still needed in stability, examination and software.
