Zenith troposphere delay time series 2025b

Zenith troposphere delays per station are obtained through a solution in independent mode of S/X and VGOS multibaseline experiments. The full set of time series is provided in one single file. These data are constantly updated. Each file contains the mjd, the full zenith troposphere delay (in psec), its error (in psec), the a priori zenith delay (in psec), and the adjusted delay (in psec). The full delay is the sum of the a priori delay and the adjusted delay.
