This work outlines the application of ground-based GPS to climate research and

meteorology without omitting the fact that precise GPS positioning can also highly benefit

using numerical weather models for tropospheric delay determination for

applications where GPS troposphere estimation is not possible, for example kinematic and

rapid static surveys. In this sense, the technique of GPS-derived tropospheric delays is seen

as mutually improving both disciplines, precise positioning as well as meteorology and

climatology
