      Thanks for the feeback @Gkikas-LGPZ. Easy fix. Either I had originally missed it, or it was added by Windy later, but there is indeed a 250mb datapoint. All I had to do was add it in. You may need to give it a few hours to update, but I've published the change.

        Nice plugin !

        It seems you have something wrong when calculating altitude related to pressure

          Hey @EduardoSG

          sorry if I'm being slow, but what's the issue?

          z = -H * log(P/Po)

          so 500 hPa should be around 7000 m, no?

            500 hPa gph rarely observed higher than 6000m

              John, 500hPa is about 5500m

                I just use the above equation in that calculation, it's just an estimate. Is there a better equation I can use? If not, suggestions on how to approach it? It's been a while since I did this stuff.

                    There is also this NOAA online calculator with corresponding formula.

                    ¯\_(ツ)_/¯

                      Okay, added a fix for that in v0.9.2 🌨️🌞

                        Hi @johnckealy

                        I found what I think can be a bug.
                        When I change models, the sounding displayed changes differently depending from which previous model I am changing to.

                        In my region I have ECMWF - GFS and ICON, in that order from left to right
                        When I go from any of the first two to ICON, it seems to repeat on of the previous two soundings
                        When I go from ICON to any of the previous two, it shows a different sounding (the same if I go from ICON to GFS or from ICON to ECMWF)

                        In total there are three soundings, but it is not clear which one corresponds to which model because of this glitches

                        I atach two screenshots

                          Sorry about that, I thought I'd fixed this already. Thanks for reporting the bug. I've just written a fix (v0.9.3).

                          Let me know if you still see problems.
