      Well done. Very cool.

      The skewT overlaps the detail a bit, at least on my screen.

      There is an error in the console:

      Error: attribute d: Expected number, "MNaN,NaNLNaN,NaNL…".

        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).

            Same problem found here https://community.windy.com/topic/7963/upper-air-temperatures

              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.
