The GPS network has been set up by the cooperation between the GFZ (Galina Dick) and the Service d'Aeronomie (Paris, France). The data from 209 and 84 stations in the COPS domain are processes by both
Zenith total delay, atmoshperic water vapor content and zenith wet delay derived from gps (Global Positioning System) measurements by the Geoforschungszentrum Potsdam (GFZ) within the EUMETNET GPS water
The ZTD (mm) is the 0-level product of the GPS data processing. It should be used for assimilation purpose. The IWV (kg/m**2) is the 1-level product of the GPS data. The conversion from ZTD to IWV is
The zenith total delay ZTD (mm) is the 0-level product of the GPS data processing. It should be used for assimilation purpose. The integrated water vapour IWV (kg/m**2) is the 1-level product of the GPS
