UK Heating & Cooling Degree Days by Grid Region
Daily heating and cooling degree days (base 18 °C) for the UK National Grid regions, computed from NASA POWER daily mean temperature. The temperature-normalized demand proxy behind GB gas and power load models - pairs with the Elexon/BMRS feed.

Built only from a named, redistributable official source under a documented open licence - not scraped web data. No copyright grey zone, no personal data. Ships machine-readable Croissant metadata (ML Commons - loads in Hugging Face / Kaggle / Google), an AI training-licence manifest documenting source, licence and provenance for your model's data governance, and a machine-readable data dictionary (drop it into an agent / RAG prompt so the model knows every column) - all inspectable before you buy.
What's included
- HDD = max(0, 18 - T_avg), CDD = max(0, T_avg - 18), base 18 °C, daily
- UK grid regions, 2015→present, keyed on GB region codes
- Derived from NASA POWER temperature - the GB gas/power demand driver

European Heating & Cooling Degree Days
Daily heating and cooling degree days (base 18 °C) for European power-market zones, computed from NASA POWER daily mean temperature. The temperature-normalized demand proxy behind every gas and power load model - aligned by ENTSO-E zone code with the catalog.
European Weather by Power
Daily weather across 15 parameters - air temperature (mean/max/min), wind speed (10 m + 50 m hub-height) + direction, cloud cover, solarirradiance, relative humidity, dew point, precipitation, surface pressure and soil moisture (surface, root-zone & profile wetness) - for European power-market zones (ENTSO-E codes), at each country's centroid, from NASA POWER. Keyed on the same zone codes as the rest of the energy catalog so it joins prices, load and generation 1:1 - the weather drivers behind every demand and renewable forecast.
Global Weather by Country (~55 nations)
Daily weather across 15 parameters - air temperature (mean/max/min), wind speed (10 m + 50 m hub-height) + direction, cloud cover, solarirradiance, relative humidity, dew point, precipitation, surface pressure and soil moisture (surface, root-zone & profile wetness) - for ~55 countries across every continent (all G20 plus much of Europe, Asia, the Americas, Africa & Oceania), at each country's centroid, from NASA POWER. Keyed by ISO-2 country code so it joins the global-country-profile and the macro catalog 1:1 - the climate layer under global growth, energy and agriculture models.
