GNSS Meteorology
A scientific method that retrieves atmospheric parameters by measuring the propagation delay of satellite navigation signals (e.g., GPS) as they pass through the troposphere. It estimates meteorological variables such as precipitable water vapor and is widely applied in numerical weather prediction.
