基于IGS超级跟踪站的近实时GPS气象研究及应用

Near real-time GPS meteorology research and application based on IGS ultra tracking stations

目前国内许多城市开始将CORS综合应用网服务于气象部门,为给地基GPS气象研究人员提供一个真实的研究环境,本文基于IGS超级跟踪站网络搭建了一个近实时GPS气象系统,并结合实测数据验证了该系统的有效性。基于该平台可以系统地研究GPS遥感水汽、层析水汽三维分布、数值天气预报同化GPS水汽以及利用电离层分布进行空间天气预报等理论。

At present, CORS comprehensive application network arc being used in weather prediction in many cities. In order to provide a real platform for researchers, we have developed a near real-time GPS meteorology system and validated the system using real IGS datasets. The system may be used to study GPS PWV, three-dimensional distribution of PWV by tomography, assimilation of PWV into NWPM and so on.
