Climate Heat Signals (derived)
Daily heat-extreme signals derived from NASA POWER daily weather for 54 world cities (2020-01-01 to yesterday): 3-sigma heat-anomaly flags against day-of-year climatology, heatwave streak counts, 30-day temperature volatility, 63-day warming momentum, naive seasonal 1-month forecasts and a per-day cross-city heat-anomaly rank. Cities are mapped to ISO country codes so the signals join cleanly with country-keyed macro data. Raw weather: NASA POWER.
Metro heating/cooling degree days, weekly (derived)
Weekly heating and cooling degree days (base 65F) for 20 North-American metros (15 US + 5 CA), 2016-2025, computed from NOAA NCEI Global Summary of the Day daily station observations at each metro's primary international airport. Ships ML-ready derived features: weekly HDD/CDD sums, heating/cooling season flags, year-on-year changes vs the same ISO week, anomalies vs the trailing 10-year same-week mean, and heat-wave / cold-snap flags at the metro's 90th percentile. Station (USAF, WBAN) identifiers from the NCEI ISD-history roster, verified 2026-09-29.
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.
NOAA National Centers for Environmental Information
Daily observed-weather demand panel for 15 US metros from NOAA NCEI GHCN-Daily, fetched keyless two ways: the trailing 365 days of observed TMAX/TMIN, precipitation, snowfall, snow depth and wind at the metro airport station via the NCEI Data Access Service (daily-summaries), and the 10-year (2016-2025) day-of-year climatology baseline from the per-station bulk files. Per (date, metro): daily mean temperature, HDD18/CDD18 degree-days, temperature and precipitation anomaly z-scores versus a 10-year (2016-2025) day-of-year climatology, heat-wave / cold-snap / heavy-rain / snow-day / high-wind flags, a pleasant-day flag, and a documented 0-100 weather-demand score with per-day cross-metro rank — high means pleasant foot-traffic/shopping weather. Same 15 metro keys (ICAO) as metro_degree_days / metro_daylight_intel for 1:1 joins; the 5 Canadian metros are excluded because GHCN-Daily's Canadian airport stations are stale in NCEI's feed. GHCN-Daily is U.S. federal public domain (commercial reuse allowed); source: NOAA National Centers for Environmental Information.
North America city weather panel (daily)
Daily observed weather for 18 Canadian metro stations (Toronto, Montreal, Vancouver, Calgary, Ottawa, Edmonton, Winnipeg, Quebec City, Hamilton, Kitchener, London, Victoria, Halifax, Saskatoon, Regina, St. John's, Kelowna, Moncton) from ECCC climate-daily observations (MSC GeoMet OGC API, keyless). Trailing 370 days, updated daily: max/min temperature (degC), precipitation (mm), snowfall and snow depth (cm), heating/cooling degree days (base 18 degC, ECCC published) plus ML-ready flags — heatwave (tmax>=32), deep freeze (tmin<=-15), heavy precipitation (>=25mm). ECCC 'M' (missing) flags become NULL, never imputed.
Daily observed weather for 20 US metro airport stations (New York, Los Angeles, Chicago, Houston, Phoenix, Seattle, Miami, Boston, Atlanta, Dallas, San Francisco, Washington, Denver, Minneapolis, Detroit, Philadelphia, St. Louis, Nashville, Portland, Las Vegas) from NOAA GHCN-Daily (keyless .dly files, public domain). Trailing 370 days, updated daily: max/min temperature (degC), precipitation (mm), snowfall and snow depth (cm), heating/cooling degree days (base 18 degC, computed from the daily mean) plus ML-ready flags — heatwave (tmax>=32), deep freeze (tmin<=-15), heavy precipitation (>=25mm). GHCN -9999 (missing) becomes NULL, never imputed.
Daily solar and meteorological parameters for 54 world cities from NASA's POWER API (sources: SYN1deg, MERRA-2), 2020-01-01 to yesterday: air temperature (mean/max/min), precipitation, relative humidity, wind speed (10 m and 50 m) and direction, surface pressure, and all-sky / clear-sky surface solar irradiance plus total photosynthetically active radiation.
