      Sounding is a diagram that shows the vertical distribution
      of temperature, humidity and wind into the atmosphere.
      Usually the observations are made by radiosondes
      (instruments carried into the atmosphere by a weather balloon).

      Weather models can give us forecast data of the same parameters
      so we can prepare "forecast soundings".

      Soundings are used by (glider) pilots to know thermals, winds aloft, icing forecast etc
      and by meteorologists (and weather enthusiasts) for rain/snow forecast,
      fog forecasting, turbulence, cloud bases/tops, thunderstorms etc

          How do I open it? I can't seem to find it....
          By the way, Airgram seems to be much faster now, great job!

              Yes!
              Pilots expect turbulence/icing forecasts,
              farmers, soil temp. at varius depths and soil trafficability
              mariners, sea/lake ice cover,
              fighter pilots, absolute humidity (for targeting with IR weapons)
              people with allergies, pollen forecasts
              etc etc :-)

                  I'm guessing the two diagonal grey lines DALR and SALR ?

                    there is a high slider om the right side

                      The moveable line showing altitude, wind speed, dewpoint and temperature is really useful but seems to be erratic or even random in it's behaviour, if you can get that right it will be perfect!

                        This tool is great for basic assessment of the wind profile. It would become powerful if the data displayed on the chart could be exported at some resolution like 500'/1000' to feed physical models for, say, high-altitude balloon trajectory planning. Any possibility of such a function to be deployed?

                                    I am impressed by every new feature you implement but this outshines everything! Thank you very much for this tool!
                                    For optimal forecasting performance I would appreciate an option to change the diagram type from Stüve to Skew t-log p. In addition, dry and wet adiabatic lines would be very helpful for better estimating instability (see picture below for an example). Do you plan to add these options?

                                          @gillie-0 The whole diagram shows dependency of various things depending on height and temperature. The right colored line(red ) is predicted temperature based on height. The left (blue line) shows dew point i.e. temperature at which will condense water in given height. If those two lines are in any point close to each other it will meant that at this height there will be clouds/fog, further they are apart there is smaller probability of clouds.

                                          Then there are two grey lines the shallower one shows how much would cool the air with height if there were no condensation (i.e. not in cloud) the steeper one shows how it would cool if condensation would occur i.e in a cloud. Now imagine you have the bag of air and you fly with it. It will cool quite fast when going up because of expansion (gases cool down when they expand) and it would cool exactly along the shallower grey line, up until you would hit dew point (the water would start to condense), and from that point it would cool along the steeper grey line.

                                          And that is it. Now you can predict storms;), if your bag would cool slower than the red line with height, it would get warmer relative to surroundings and warm air goes up so it would be warmer and warmer, and it would go faster and faster up and thats how storms are created, a lot of warm air goes up with all the moisture which then goes down as rain.

                                            @fx-eddh there are dry and moist adiabates but only two (those two grey lines)
