Tropospheric parameters derived from the selected IGS stations in the global tropics for the years 2001-2018

Description

This dataset contains daily GNSS-derived zenith tropospheric delay (ZTD), a posteriori corrected zenith wet delay (ZWD), and precipitable water vapour (PWV) time series. These troposphere-related data were estimated for the period between January 2001 and December 2018, for the 43 International GNSS Service (IGS) stations, located in the global tropics. Calculations were carried out using Bernese GNSS Software ver. 5.2 and the precise point positioning (PPP) approach. Tropospheric parameters were estimated using the Vienna Mapping Function 1, Saastamoinen model, and meteorological fields derived from the ERA5 model. This dataset states for the source of the long-term tropospheric time series, which can be used in meteorological and climate studies. It enables for the examination of the moisture pattern on numerous time scales, including seasonal and interannual variability.
