| 摘 要： | 根据全球定位系统遥感水汽的原理,利用2004年6月哈尔滨GPS跟踪站的观测资料和气象资料,对哈尔滨地区的大气综合水汽含量进行了反演,得到了误差(与控探空资料计算的水汽含量相比)为2.7 mm的反演结果。同时对影响水汽反演的误差进行了分析,给出了各项误差对水汽结果的影响程度,并对反演结果与探空资料结果和实际降水进行了比较,得出了其间变化一致性的结论。

| Abstract: | The principles of GPS-based water vapor remote sensing are introduced.The atmospheric integrated water vapor content over Harbin was retrieved by means of the measurements of the Harbin GPS station in June 2004,and the results with the error being 2.7 mm(comparing with the computed water content by radiosonde data) were obtained.The errors and the influence degree on the precipitable water vapor results are analyzed.Comparison is conducted between retrieved and observed,as well as the radiosonde data.The findings conclude that the retrieved results are applicable. |
