What is represented?

  • This map represents the hourly-updated Zenith Wet Delay (ZWD) estimated with a time resolution of 15-min based on a network of GNSS stations. This ZWD corresponds to the Zenith Total Delay (ZTD) estimated et the GNSS stations minus an a priori model (Saastamoinen).
  • The map is calculated using the Kriging interpolation method.
  • The ZWD points layer represent the (exact/non-interpolated) ZWD value at the GNSS stations.
  • The Variance layer is stemming from variance computed during the kriging interpolation method.
