NASA POWER
Daily heating/cooling degree-day panel for the 20 North-American prediction metros (15 US + 5 CA), from keyless NASA POWER daily 2-meter air temperature (2020-01-01 -> latest POWER day, ~2-day lag). Daily HDD/CDD (base 65F), trailing 7/30-day thermal loads, same-day-of-year anomalies vs a trailing-5-year baseline, heat-wave/cold-snap flags (metro 95th percentiles), season flags, and a documented 0-100 thermal_demand_score. The current daily companion to the weekly NOAA-GSOD metro_degree_days panel (which ends Aug 2025). Joinable by (date, metro) to Shopify/Stripe/HubSpot data. Caveats: POWER is a reanalysis/model blend, not station observations; first 6 days per metro lack a 7-day window (NaN, never padded); anomaly baselines need 3+ prior same-doy years. NASA US-government data, no copyright restriction (CC0-1.0), commercial use allowed.
