Met Office DataPoint / CEDA
The Centre for Environmental Data Analysis (CEDA) is the UK's home for atmospheric and Earth observation data. Its archive brings together Met Office records, climate model outputs, and satellite data in one place.
Licensing varies by dataset. Much of the archive is available under the Open Government Licence, which permits reuse, including commercial use, with attribution, but some collections carry their own terms. Check the licence on each dataset before you build on it.
