Abstract

The use of Numerical Weather Models (NWMs) provides forecasts of meteorological events based on hypothesis on surface cover, boundary layer and other mechanisms of atmosphere processes. In many cases, the selection of appropriate parameters and the tuning of models at the basis of NWMs is made by non-advanced users in a hoc manner. The availability of huge databases of InSAR and GNSS measurements of PWV provides those users a unique possibility to falsify the hypothesis at the basis of their choice of parameters. In this work we introduce features, based on statistical analysis and graph theory, that can help to compare InSAR and GNSS measurements to NWM simulations. From the point of view of the user, the meaning
of comparison is to quickly catch the informative potential of InSAR and GNSS data if assimilated in a NWM.
