【摘要】 随着地基GPS技术日益完善以及GPS气象学研究的迅速发展,地基GPS探测技术已经成为一种有效的大气水汽探测手段。和传统的手段相比,地基GPS探测技术具有精度高、覆盖范围广、可全天候连续观测、时间分辨率高、成本低等优点,因此受到了国内气象部门的极大重视。利用GPS进行大气探测正逐步向业务化过渡。但目前还没有完全达到应用阶段,还有很多的技术问题有待进一步解决。以广东省GPS气象监测网建设项目为基础,对地基GPS大气水汽探测的原理、方法进行了探讨。更多还原

【Abstract】 With the increasingly sophisticated of ground-based global positioning system(GPS)sounding technology and the rapid development of GPS meteorology research,ground-based GPS sounding technology has become an effective means of atmospheric water vapor detection.Compared with traditional methods,ground-based GPS sounding technology has advantages such as high accuracy, wide coverage,all-weather continuous observation,high resolution and low cost.It has been emphasized by the national meteorological departments.Atmospheric detection using GPS transits to the operational stage gradually,but not fully reached the application stage yet,there are many technical problems to be solved.Principles and methods of ground-based GPS atmospheric sounding is discussed based on GPS meteorological monitoring network construction project in Guangdong in this paper.更多还原
