Oblique ionograms derived from the current vertical incidence ionogram measured by the Digisonde at Dourbes (50.1 N, 4.6 E) on 2022-10-10 at 13:30 UTC.
The actual Operational MUF for the x mode wave for each radio path is indicated.
Es traces are not plotted for frequencies higher than 40 MHz. The highest Es MUFx values for 1 hop and 2 hop links for any of the 10 radio paths are shown in a table.
Note that all ionograms only apply to radio paths where Dourbes is at the centre of the path.
Oblique ionograms are available for Dourbes, Juliusruh, Pruhonice and Sopron.
