摘 要: | 利用GAMIT软件选取了10个IGS站和2个基准站对2003~2007年北京GPS部分观测数据进行了解算,验证解算精度达到要求后反演出各测段内时间分辨率为1h的大气可降水量序列,并与无线电探空仪获取的探测结果和气象局解算的GPS数据分别进行比较。根据二者线性拟和关系发现初步结果趋势一致,可应用于下一步建立大气延迟改正模型。

Abstract: | Using the GAMIT/GLOBK software and selecting 10 IGS stations & 2 datum stations to process the GPS observation during 2003-2007 in Beijing,this work get the troposphere delay and the zenith wet delay.Then the precipitable water vapor(PWV) with the temporal resolution of 1 h has been retrieved.Compared with the results detected by radiosonde and GPS data from observatory,the results indicated that the primary results were similar according to the linear fitting relations,which could be further applied to establishing the delay and correcting model for ZTD. |
