During last two decades, Global Navigation Satellite System (GNSS) has proved to be an efficient and weather-independent technique for a monitoring of the troposphere. Recently, real-time tropospheric products became available too. The GNSS products from the post-processing and (near) real-time solutions are also convenient for a long-term assessment and early monitoring of numerical weather predictions (NWP). In July 2015, we thus started a routine generation of GNSS tropospheric parameters in real-time using a mesoscale NWP model. Additionally, we evaluated NWP-derived tropospheric parameters with respect to the length of the prediction. The accuracy of 9.5-13.4mm for ZTD corrections from 0-18 h predictions promise a potential use of NWP-based tropospheric corrections in GNSS real-time positioning and navigation applications.
