The values are way off (ie gh-900 should be a little below 1000m).
It look like they are off by a factor of 10 ?

Thanks @ivo

So the "better" way to retrieve favorites is

import favs from "@windy/favs"; 
// or
// var favs = W.require('favs');

Then

favs.getAll();

returns:

{ 
  "34.492/-119.702": {key: "34.492/-119.702", lat: 34.491843, lon: -119.702396, name: "Santa Barbara", type: "fav", …},
  "36.768/-119.098": {key: "36.768/-119.098", lat: 36.768385, lon: -119.097719, name: "Dunlap", type: "fav", …},
  …
}

and

favs.getArray();

returns:

[
  {key: "37.514/-121.882", lat: 37.513810842731, lon: -121.88215255737303, name: "Mission Peak", type: "fav", …},

Go to "https://www.windy.com/-Settings/settings" (settings menu)

You can setup the strartup location to be ip /gps / one of your favorites

Check exemples 10 and 7 at https://github.com/windycom/windy-plugins

@CR check https://en.m.wikipedia.org/wiki/Level_of_free_convection

I'd love to see more info about the available data too.
May be the plugins repo on github would be a good place to add them ?

I use u & v interpolations.

There is one gotcha when you do angle interpolation wrt to wrapping: avg(310, 50) is 0 not 360 / 2.

@Gkikas-LGPZ Units should be what you have configured in windy settings - I'll add them on the graphs at some point.

There are quite a few things I want to improve/polish and then I'll get the android app you pointed to. Thanks !

Hey @johnckealy,
It is possible that you are referring to me in your last comment ?
I have released windy-plugin-sounding a few days ago.
I took inspiration from your plugin for the computation of the adiabatic lines - thanks :)

You can check the code at https://github.com/vicb/windy-plugin-sounding
It's still an early version.
My plan is to make the code more modular. Maybe we could work on some common components.

Let me know when you have time for pairing on that.

@johnckealy right click anywhere on the map and select (the bottom most item) "Better sounding"

@ivo I'm all for it if possible. As @Gkikas-LGPZ mentions the sounding is more adapted for paraglider pilots currently and I probably need to make some small changes:

• The upper is currently set to 400hPa, changing it is only a setting,
• The wind scale is non linear (0-30km/h on the left half, 30 to max on the right half),
• I have done nothing to make it work on mobile screens.

All of this should be easy enough and there could be a setting to have a generic version or a specialized version for paraglider (a checkbox).

@Gkikas-LGPZ as mentioned above the current upper level is 400hPa but that's only a setting to change. I have just checked for the units. It seems like "ft" does not work ie altitude is always displayed in meters but "kt" works for me for the wind (You have to reload the page & plugin when you change the units). There is currently no way to have hPa on the y axis but that would be simple to implement.

@Gkikas-LGPZ please check 0.8.2 that I have just published:

• Changing the units in the preferences should now work for altitude,
• There is a check box ("Zoom view") at the bottom to expand to graph up to 150hPa (zoomed view is up to 400hPa).

You probably need to specify the name as sounding@0.8.2 when loading it for now.

@stitch good catch. The line was still potted with the wrong scale in unzoomed mode. This should be fixed in 0.8.5. (You can specify the version when loading the plugin using the name windy-plugin-soundig@0.8.5 before it becomes the default in a few hours).

With regards to the scale in zoomed mode:
The plugin is originally targeted to paraglider pilots.
That's why I do not display hPa but elevation on the y axis and stop at ~7000m.
Given that a paraglider fly at ~40km/h we are less interested in speed > 30km/h - we would start flying backward in gusts and also have turbulences.
That's why having more granularity in the 0-30k range is interesting - we are only remotely interested in >30.
It does not affect us that much: we wouldn't fly in that zone but knowing the max speed higher still could be interesting.

That being said I'm open to extending the plugin for more use cases - we started discussing that with @johnckealy.
What I do not want is to have to configure 20 different options to use the plugin but what I could imagine is to have a handful of different "profiles" (paragliding, meteo, ...) each having a sensible configuration.

Having a shared google doc could help everybody interested share ideas ? Do you want to start one ?

I would love to see plugin on mobile app & web too !

The intersection between the green and red lines is the top of thermals (1900ft on the screenshot) - that's how high glider pilots can expect to reach when flying.

The cursor is supposed to show the altitude - 68900 should be 21000(ft) but there was a bug with imperial units that I just fixed in 1.1.6. Thanks for reporting !
