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.

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

@ekostogorov @TZ my plugin (windy-plugin-sounding) does support skewT (uncheck the "zoom view" checkbox at the bottom). It can be loaded on mobile by visiting windy.com/plugin however it does not well yet because I need to adapt the size to mobile screen.

It should probably not take too long to do but I have deferred for now that since loading plugins on mobile (especially in the app) is not well supported.

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", …},

When using the pluginDataLoader to load airData for {lat: 43.976, lon: 6.483}

I got the following:

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 ?

@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 ?

@kekert You can use this script to extract the camera positions, url and azimuth. Let me know if you have any questions.

Thanks

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 !

@Marcelklim said in Javascript fetch:

fetch("https://api.windy.com/api/point-forecast/v2", {
method: 'POST',
body: _data,
headers: {"Content-type": "application/json; charset=UTF-8"}
})

You should try body: JSON.stringify(_data)

Thanks @Korina

I sent those info to Marek:

It seems like the parameter we are looking for is HPBL (see https://www.nco.ncep.noaa.gov/pmb/products/gfs/gfs.t00z.sfluxgrbf00.grib2.shtml variable #109) and some description of the Boundary layer in https://vlab.ncep.noaa.gov/web/gfs/documentation section 1.2.2
It's not exactly clear to me if this parameter HPBL is part of the GFS variables.

ECMWF seems to have it too: https://apps.ecmwf.int/codes/grib/param-db?id=260083

That would be a really nice addition for free flight pilots !

Is this data provided by the weather models ?

You should look at the windy repository with plugin examples.

Check this plugin.

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

@kekert You can use this script to extract the camera positions, url and azimuth. Let me know if you have any questions.

Hey,

It seems like the plugin-data-loader does not return the premium forecasts (i.e. more runs for ECMWF).

There are 2 problems:

1. by default the api send a POST request without credentials,
2. even if I force the credentials to be sent (by manually setting the option before the XHR is sent) then the same forecasts are returned instead of the latest premium ones.

Could you please consider fixing those 2 points (1 on the frontend and 2 on the backend) ?

Having the premium forecasts available in the plugin would give more incentive to users to buy premium.

Thanks

Simple repro code:

W.require("@plugins/plugin-data-loader")({
  key: "QKlmnpLWr2rZSyFaT7LpxZc0d5bo34D4",
  plugin: "windy-plugin-sounding"
})("airData", {lat: 40, lon: -120, model: "ecmwf"});

The source is http://www.alertwildfire.org/.

That's a network of camera that are used to look for wildfires on the west coast of the US. That's high quality picture on mountain tops.

See one example

I have figured how to get the URLs, positions and orientation of those cams.

Do you have an API to add 100+ webcams at once ?

I seem to remember it was supported on webcams.travel but it seems like only one web cam can be added at a time on windy.com

Thanks

@MarkRD Thanks a lot.

As I replied on github you have identified a bug in the plugin. It comes from the fact that the relation between altitude and pressure is not linear.

I need some time to think about the best possible fix. Probably a few days.
