The integrative construction of GPS water vapor monitoring system

Water vapor is an important kind of greenhouse gas in the atmosphere whose spatial distribution is extremely uneven and time variation is also very fast. It is not only the main driving force of weather and climate change, but also an important formation and evolution reason for disastrous weather, especially meso-small scale disastrous weather. Along with the development of GPS meteorology, people start to utilize ground-based GPS technology in order to effectively compensate for the defects of traditional detection technologies in space and time and obtain water vapor information with high-precision, high-capacity and high space-time resolution ratio through ground-based GPS water vapor monitoring network This main content of this paper is to launch the development of ground-based GPS water vapor monitoring system; the purpose is to make this system fill in the blank of the application of GPS inversion water vapor technology in Sichuan and even the southwest areas of China, and also enhance the capacities of meteorological department on the forecasting and monitoring of meso-small scale disastrous weather, as well as promote the work of many related meteorological operations.
