ROB's operational world-wide near real-time GNSS-based tropospheric delay estimates submitted to E-GVAP

GNSS-based tropospheric delays estimated operationally in near real-time by the Royal Observatory of Belgium (ROB) - Solar-Terrestrial Centre of Excellence (STCE) in the framework of his participation to the EUMETNET EIG GNSS water VApor Program (E-GVAP). These tropospheric delays are computed every 1 hour from a world-wide network of GNSS stations with a time resolution of 15 min to support global NWP models and regional NWP models outside Europe.
