Figure 1 shows the time evolution of the Vertical Total Electron Content (VTEC) (in red) extracted from the near-real time VTEC maps at 3 different latitudes (Figure 2): a) Northern part (top), b) Brussels (middle) and c) Southern part (bottom). Also shown, the model based on the median from the 15 previous days (in grey).
