Abstract

The tropospheric delay is one of major error sources in GNSS positioning, which contributes a bias in height of several centimeters even when simultaneously recorded meteorological data are used in tropospheric models. Nowadays, GNSS has been widely used to determine the zenith tropospheric delay (ZTD) as well as precipitable water vapor (PWV). In this chapter, the theory and methods of ZTD and PWV estimations are introduced from ground GNSS observations. The seasonal, secular and diurnal variations of ZTD and PWV are presented in detail as well their applications in the atmosphere.
