Research and Application of Real-Time Water Vapor Remote Sensing Using Ground Based GPS/Met

The amount of water vapor in the atmosphere is highly variable in space and time. Flow to get real-time water vapor information and understand the variation of water vapor is to solve the urgent problems for present atmospheric soundings. Ground-based GPS technology provides a new means for sensing atmosphere water vapor, which has become a powerful complementary to the regular atmospheric sensing system. Along with the rapid development of GPS navigation techniques and establishment of CORS Network, especially the full implementation of the Crustal Movement Observation Network of China (CMONOC), research on Ground-based GPS/Met theory and application is rapidly developing at home in recent years. But ground-based GPS/Met has not been reaching the step of normal application. Much more research work concerned about it needs to be solved in the near future. In this paper, a few key technologies of remote sensing water vapor using Ground-based GPS/MET are studied thoroughly based Summarizing systematically the theory and methods of GPS sensing water vapor.
