ROB's operational European near real-time GNSS-based tropospheric delay models, grids, and maps

GNSS-based tropospheric delays models, grids, and maps computed operationally by the Royal Observatory of Belgium (ROB) - Solar-Terrestrial Centre of Excellence (STCE) from the near real-time tropospheric delay estimated in the context of his participation to the EUMETNET EIG GNSS water VApor Program (E-GVAP). These tropospheric delay maps are generated according to the characteristics of the ROB contributions to E-GVAP (e.g. the models, grids, and maps corresponding to the ROBH contribution focus on Europe, are updated hourly and have a time frequency of 15 min). The spatial resolution of the models, grids and images is 0.1° x 0.1°. In parrallel, high spatial resolution models, grids, and maps over Belgium and its surrounding are also generated.
