Oblique ionograms - Pruhonice

Oblique ionograms derived from the current vertical incidence ionogram measured by the Digisonde at Pruhonice (50.0 N, 14.6 E) on 2017-11-18 at 13:00 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 Pruhonice is at the midpoint of the path.

Oblique ionograms are available for Roquetes and Pruhonice.


For further information see the info page.
