Wind Barbs Request
You only need to specify this style URL in your client and it will automatically know what other URLs request for other resources such as vector tiles and wind barbs icons:
https://api.meteomatics.com/mvt/barbs/<parameter>/style.json?<optionals>Only wind speed in knots are supported, for example:
For example, below is the result for https://api.meteomatics.com/mvt/barbs/wind_speed_100hPa:kn/style.json?datetime=now
And for a colored version https://api.meteomatics.com/mvt/barbs/wind_speed_100hPa:kn/style.json?datetime=now&color=true
