The World Meteorological Organization has data that national weather services exchange to make forecast. Apart from that, its on a country-by-country basis.

In France for instance Météo-France has released all of its historical data in January 2024: https://www.data.gouv.fr/fr/organizations/meteo-france/#/dat...

But national models go beyond there borders and usually have some modelling outside so the exchanges will cover quite a lot of the world.

For example, the UK's metoffice has a low resolution medium term global model: https://www.metoffice.gov.uk/research/approach/modelling-sys...

How does windy do it? Did they just scrap all the sites or api. Would be great to have global dump every 1 minute of all the countries. Or have it have in a radio broadcast.

Windy uses openmeteo, which in turn aggregates many weather providers under one roof/api
