Four analysis centres processed the GPS data and, in addition to daily station coordinates, estimated tropospheric signal delays in the form of zenith total delays (ZTD). Here we provide the resulting time series of ZTD for each station and from each analysis centre. The TUD, OSU and UTAS analysis centres provide time series with a temporal resolution of one hour, while the NEWC solutions have a resolution of two hours. The dataset consists of tab-delimited text files, with each file named using the following convention <station_id>_GR2023_ztd_<ac>.tab. The <station_id> is a unique identifier for the GPS station within this dataset consisting of the four character site code and the IERS domes code (if assigned to the station), <GR2023> refers to the GIANT-REGAIN project, <ztd> denotes the zenith total delay, and <ac> indicates the analysis centre (newc, osu, tud, utas).-155.022892178.047113-87.415655-54.003231
