6632 20240123114008.0 DATASET-2024-0012 Pottiaux, Eric ROB's operational quasi-real-time GNSS-based tropospheric delay models, grids, and maps (from 1 Jan 2023 until 31 Dec 2023) 2023 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 quasi-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 quasi-real-time ROB contribution to E-GVAP (i.e. the models, grids, and maps corresponding to the ROBQ contribution focus on the BENELUX and U.K., are updated every 15 min and have a time resolution of 15 min). The spatial resolution of these models, grids, and images is 0.1° x 0.1°. In parallel, high spatial resolution (0.05° x 0.05°) models, grids, and maps over Belgium and its surrounding are also generated.
