Fig. 6From: 2D PWV monitoring of a wide and orographically complex area with a low dense GNSS networkPWV (a) and ∆PWV (b) values for the G4M (green) and WRF (blue). The orographic effect was successfully removed from the ∆PWV graph. The position of the section is depicted in the top right of the figure. The x-axis displays the distance in kilometers, from the start of the section (red dot) from west to east; the y-axis shows the PWV and ∆PWV valuesBack to article page
