Comparison of the wet component of zenith tropospheric delay derived from GNSS observations with corresponding value from radio soundings
The purpose of this paper is to evaluate an accuracy of the wet component of zenith tropospheric delay obtained by the data of six GNSS stations in comparison with radio sounding data. The determination of hydrostatic and wet components of zenith tropospheric delay was divided into several stages. In the first phase, with an appropriate site for data center processing GNNS-measurements averaged values of zenith tropospheric delay were selected.
