| Abstract: |
| Ground-based GNSS water vapor tomography technology is an important branch of GNSS meteorology. This technology enables the inversion of the three-dimensional atmospheric water vapor field, which is of great significance for extreme weather monitoring and meteorological disaster warning and forecasting. Over the past 30 years, ground-based GNSS water vapor tomography technology has gradually developed a relatively comprehensive theoretical and methodological system, achieving high precision and high temporal-spatial resolution inversion of three-dimensional water vapor information, and has seen more and more innovative applications in atmospheric water vapor monitoring and precipitation warning and forecasting. The research status of ground-based GNSS water vapor tomography technology is comprehensively reviewed and summarized in terms of the construction of the design matrix of the tomography model, the use of the observation data of the tomography equation, the calculation of the water vapor tomography model, the analysis of the influencing factors of the tomography results and their applications, and the future development direction is analyzed. |
