      I have seen some radiosondes in which the shading in the left where the pressure levels are, seems badly represented.
      I understand this shading represents cloud cover
      Here is one example

          These soundings are sounding measurement from a sounding station. So the data is provided by the station. Same for the cloudiness shown on left side ?

            As far as I know, the shading is derived from the relative humidity.
            Over 85% BKN
            Between 65% and 85% FEW to SCT
            Under 65% no clouds
            So the shadings in your examples seem to be buggy as the soundings are quite dry.

              @idefix37 OK, I thought the shading was a Windy feature as I cannot see it in other sources of radiosondes

                @wetterheidi Exactly!! That is why it is obviously wrong

                  Sorry my post is probably not clear I must admit. I put a question mark at the end of it. So I don’t know precisely the source of this cloudiness.
                  I just see that the Sounding measurement from sounding stations shows it but not the Sounding forecast which is computed by Windy from the weather model data.
