      Amazing feedback, thanks everyone!

      @rittels, the skewT is overlapping the spot forecast? I'll look into that. Man I hate cross-browser incompatibility! The error you see isn't anything to worry about, been meaning to find a way to suppress it. It's just the data points in the ascent that I didn't want shown.

      Thanks for the info on the temperature discrepancy too @Gkikas-LGPZ and @Yves70, I'll have a look into that for the next version.

        Hi All,

        windy-plugin-skewt now has a radiosonde feature. I'm still testing it, but please let me know any feedback :)

          Wrong data for 250hPa (FL340).

          It seems your plugin doesnt take into account data for 250 hPa (nor interpolate 300~200 hPa data).

            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.
