These tropospheric delay maps are generated according to the characteristics of the ROB's operational European NRT 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 parallel, high spatial resolution models, grids, and maps over Belgium and its surrounding are also generated.
