地基BDS/GNSS水汽监测在水利领域的研究进展与展望OA北大核心

Almost all water vapor on Earth is concentrated in the troposphere,the content of it has a significant impact on global temperature,precipitation,and other meteorological factors,which can to some extent affect Earth's climate change and regulate heat balance on a global scale.Tropospheric water vapor monitoring plays a crucial role in water resource management,extreme weather warning,and climate change research.In the process of continuous development and improvement of BDS/GNSS global satellite navigation technology,the retrieval of precipitable water vapor by BDS/GNSS has gradually become a new type of water vapor detection technology.Compared with traditional water vapor detection technology,BDS/GNSS can achieve high-precision and near real-time monitoring of water vapor.To deepen researchers'understanding of BDS/GNSS precipitable water vapor(PWV),the paper provides a systematic review of the development process and research status of the retrieval of BDS/GNSS PWV,elucidating its inversion principles and methods.It mainly analyzes the application and development direction of ground-based BDS/GNSS water vapor monitoring in the field of water conservancy from high-precision water vapor monitoring,short-term and imminent rainfall forecasting,climate change,and drought & flood monitoring.
