Thanks for your post @Samygallego

I have had the same feedback from many paraglider pilots: AROME would be awesome.

PG pilots have little interest in surface conditions, what they are looking at to check the conditions is the sounding forecast - that's why many users complained about the v42 update when the plugin sounding stop working for a few days before I had time to update the plugin to the new API.

AROME covers the Alps where thousands of people are flying on good day. Here in France meteo-parapente.com is popuplar because it uses the AROME model but the UI is way less friendly than windy.

Please switch to AROME 2.5 🙏.

Windy is the best ❤️

I have created a plugin to display soundings for paraglider pilots.

You can try it by installing windy-plugin-sounding.

It's still in early stages - feedback welcome.

Thanks to John C. Kealy - I borrowed some code from his skewt plugin.

@Suty I'm on it.
People can contribute code, good karma, or money via buymeacoffee.com/vic.b
The later option might yield a faster availability :)
It should be ready within a week

I'm making progress on the sounding plugin. I still have some work to do on the mobile UI and a few things here and there but I should be able to publish an ok version most probably on Friday - the sounding looks good for tomorrow and I'll go check if it's not a bug :)

Thanks for your patience.

Thanks to the windy team for this awesome site and platform.

I have just seen that the webcams are online.
Thanks !

@Silversurfer75 je ne pense pas qu'une grille a 2.5km soit gênante en plaine?
Comme le dit @Samygallego les prévisions sont exactement les mêmes. La seule différence est la résolution de la grille.
Il me semble donc que arome2.5 serait mieux pour tout le monde?
Samy (qui est ingénieur prévisionniste chez MF) pourra sûrement nous éclairer un peu plus.

The plugin now works better on mobile and tablets.

As a reminder plugins do not work on the installed mobile apps but you can use them by loading windy in a web browser on your mobile or tablet.

Visit https://www.windy.com/plugins/windy-plugin-sounding to load the plugin on a mobile device.

It's related to a windy.com change.

v4.1.13 was released to fix this, updating should fix any issues.

Let me know otherwise.

@klssoaring It's not 6knt - the layer shows top of lift (meters or ft)

@Berthold-Bär That's something I discussed with Marek in the past.

soaringmeteo.org has some open source code to compute the thermal speed. I'm not sure if all parameters are available in windy or if they can be added?

Maybe @Filip_K knows?

The PG community would for sure love to see this!

(I was discussing that last week with Simen Eide - a meteorologist. @Samygallego is an other talented meteorologist that might have some ideas)

Edit: Simon is actually a mathematician but he knows a meteolorogist :)

@francescogola the plugins update automatically (for the past few months)

@nrbray I commented about this here.

TL;DR Plugins have access to data at different level, the lower one being gh-1000. There is a gh-surface but I'm not sure if we should use this for soundings - they are about the air mass not the ground. I'm not exactly sure what sh-surface is. I asked on the thread I linked above but got not reply.

@ghuyt-rfffgh-fhiij-xiagua I guess the question is what would you like to see that the current 3D does not do?

Hey @Rubilin

I'm the author of the "flyXC soundings" plugin.

I believe this is a bug in the built-in soundings. I recently updated the code of the plugin to fix this - @marekd told me to add {extended: "true"} when fetching the forecast data. After I updated my code the plugin was able to access the full time range.

The technical details in this post are not aiming at confusing you but to help the windy team fix the issue quickly. @Suty might be also to help route to the right person.

In the meantime you can use the flyXC soundings plugin, the zoomed out view is similar to a regular sounding.

Turns out the Chrome package repository was disabled when I upgraded to Ubuntu 24.04. I have re-enabled it and updated Chrome. Everything works like a charm now.

I have released v4.0.0 of the plugin yesterday.

It's now called flyXC soundings.

There are many improvements to the UI and even more changes under the hood.

I have written a longer post on the flyXC facebook page.

I'm pasting the last sections of the post below:

There are a few ways you can help the project:

• the README linked above is succinct. I would love some help with writing a nicer documentation
• you can also contribute code if there a feature you would like to see added - if you do not know how to code, you can still contribute ideas
• lastly you can sponsor the project. While the sounding plugin (as well as flyxc.app) is open source, it's nice to get some money to compensate the hours spent developing it

Do not hesitate to message me if you want to help.

Many thanks to windy.com for their awesome website and maintaining the plugin framework. Many thanks to John Kealy, his SkewT plugin released in 2019 was a great source of inspiration.

The plugin just shows heights; are these heights just calculated from temp-1000h, temp-900h

They are calculated using the gh-1000h, ... (geopotential height)

Regardless, if it is valid, is there any data missing or is it still possible to calculate the points on the diagram?

Yes, it's possible to compute those values and it's called a weather model ;)

Can the model elevation be used for the surface data? (The builtin sounding shows the model elevation, but perhaps the plugin doesn't have access to this?)

The plugin has access to the same data. But again I don't think surface can be used (to be verified)

The Meteoblue temperature and dew point lines always starts at 1000hPa, and it also shows a horizontal surface pressure line. All the other examples start at the surface pressure, whatever that is for the particular location and time.

I think some models provide a temp-100m, ... which could be helpful. This is not part of the data provided by windy.

Maybe @marekd knows more?

Thanks for the screenshots, the ensemble graph on ECMWF gave me the idea to overlay multiple models on the sounding.

@vicb

I did clear all the site data and still see the issue. I traced it down.

On logout, we enter

which calls

e === null and returning a resolved promise crashes the tab.

I checked in Firefox and this yield b1() works fine.

Probably a chrome bug?

@jancellor

I have been looking into this while updating my plugin and it's actually not trivial.

Weather models output is a list of parameters at different pressure levels. For example temp-1000h, temp-900h, ..., temp-100h. The only value below 1000hPa is temp-surface.

I'm sure if temp-surface can be used for the soundings. Soundings are about the air mass and I think the surface level is well the surface and not the air above the surface. Also if I remember correctly there were some discussions to remove that level.

Maybe @Suty can help connect with someone at windy that would be more knowledgeable than me on that topic.

For now I'll sticks with 1000hPa for the sounding plugin and I'll update if we get more info.
