Assimilation of Zenith Wet Delay Observations Using the Ensemble Kalman Filter in a Poly-ZWD Empirical Model Over the USA

Journal of Atmospheric and Solar-Terrestrial Physics
Modeling the spatial and temporal variability of water vapor in the lower atmosphere is crucial for meteorological and geodetic applications, as it directly influences weather prediction and satellite-based positioning. However, traditional empirical models often struggle to capture rapid water vapor fluctuations, limiting their accuracy and practical ...

Establishment and Assessment of a Zenith Wet Delay (ZWD) Augmentation Model

GPS Solutions, 2021
The zenith wet delay (ZWD) accuracy is one of the most important factors affecting the convergence time and the positioning precision in precise point positioning processing. Taking into account the limitation of the empirical and blind ZWD models, the correlations between the ZWD and temperature and water vapor pressure at each point of the global 1o ×
