Impact of GPS Zenith Tropospheric Delay data on precipitation forecasts in Mediterranean France and Spain [PDF]
Forecasting precipitation in the western Mediterranean is difficult because of the interactions among dynamical forcing, orographic lifting and moisture advection from the warm Mediterranean Sea. Torrential rainfall events are not uncommon, especially during the autumn.

Adaptive neuro fuzzy inference system for predicting sub-daily Zenith Wet Delay
In recent years, the focus of tropospheric studies has evolved to GNSS meteorology and weather forecasting. The Zenith Wet Delay (ZWD), which might be assembled to the Integrated Water Vapour (IWV), is an essential component of the tropospheric delay ...

In the GNSS analysis the signal travel time delay induced by the neutral atmosphere is parameterized. The related parameters are derived from a climatology or better yet from a Numerical Weather Model (NWM). Current thinking is that NWMs are not accurate

Tropospheric delay error is independent of the signal's frequency and has strong spatiotemporal variation. It is one of the most severe error sources of satellite navigation and spatial measurement. In view of the limitation of global zenith tropospheric

Short-term precipitation forecasting based on the data from GNSS observation
The Precipitable Water Vapor (PWV) derived from Global Navigation Satellite System (GNSS) can be used for the study of precipitation forecasting, but it needs the support of ground measured meteorological data. In order to solve this problem, a method of

Modeling tropospheric zenith wet delays in the Chinese mainland based on machine learning
In this study, the tropospheric zenith wet delay (ZWD) modeling was realized based on the regression analysis of 7 years (2013–2019) of radiosonde data at 182 sites in the Chinese mainland and the surroundings through two machine learning (ML) approaches
