Wind direction
Dear Tygron,
Just checking if the wind direction parameter in the heat overlay refers to the direction from which the wind blows (meteorological convention) or the direction the wind blows towards (oceanographic convention)?
I'm not a 100% sure reading the wiki (https://support.tygron.com/wiki/Wind_direction_(Heat_Overlay))
Keen to hear from you!
Kind regards,
Glenn

Hi Glenn,
The page you reference has a link to the overall information page regarding KNMI data:
https://support.tygron.com/wiki/KNMI_Weather_data
This page, in turn, has for the wind direction parameter another link to the KNMI website which provides more information:
https://www.knmi.nl/kennis-en-datacentrum/achtergrond/klimatologische-brochures-en-boeken
Specifically, for the wind direction this document is specified:
https://cdn.knmi.nl/system/ckeditor_assets/attachments/68/windroos_metstrekenmaaroudadres.pdf
Which details at the bottom as explicit clarification: the direction from which wind blows.
I'll make sure that we clarify this more directly in the wiki's parameter description.
Regards!
