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.

Colonne	Type	Description
week_start	date	Monday starting the observation week. (unit: date)
metro	string	Metropolitan area name.
state_province	string	US state or Canadian province of the metro.
country	string	Country name (United States or Canada).
country_code	string	ISO 3166-1 alpha-3 country code (USA or CAN).
icao	string	ICAO code of the metro's primary international airport, where the GSOD station sits.
latitude	float	Station latitude, decimal degrees. (unit: decimal degrees)
longitude	float	Station longitude, decimal degrees. (unit: decimal degrees)
temp_avg_f	float	Weekly mean of daily mean temperatures in Fahrenheit. Daily mean = (MAX + MIN) / 2 when both present, else the GSOD TEMP mean; GSOD missing values are never imputed. (unit: degrees Fahrenheit)
days_valid	integer	Number of days in the week with a valid mean temperature (0-7). Weeks with fewer than 6 are dropped, never padded. (unit: days)
hdd_weekly	float	Derived: sum of daily heating degree days over the week, where daily HDD = max(0, 65 - daily mean temp F). Connector-defined transformation. (unit: Fahrenheit degree-days)
cdd_weekly	float	Derived: sum of daily cooling degree days over the week, where daily CDD = max(0, daily mean temp F - 65). Connector-defined transformation. (unit: Fahrenheit degree-days)
total_dd_weekly	float	Derived: hdd_weekly + cdd_weekly, the total weekly temperature-driven energy/demand load. (unit: Fahrenheit degree-days)
heating_season_flag	boolean	Derived: true when the ISO week is 40-52 or 1-13 (heating season).
cooling_season_flag	boolean	Derived: true when the ISO week is 22-38 (cooling season).
hdd_yoy_change	float	Derived: hdd_weekly minus the same metro's hdd_weekly for the same ISO week one year earlier. Null when the prior-year week is unavailable. (unit: Fahrenheit degree-days)
cdd_yoy_change	float	Derived: cdd_weekly minus the same metro's cdd_weekly for the same ISO week one year earlier. Null when the prior-year week is unavailable. (unit: Fahrenheit degree-days)
hdd_anomaly_vs_10y	float	Derived: hdd_weekly minus the trailing 10-year mean of the same ISO week for the same metro (min 5 prior years). Null when fewer than 5 prior years exist. (unit: Fahrenheit degree-days)
cdd_anomaly_vs_10y	float	Derived: cdd_weekly minus the trailing 10-year mean of the same ISO week for the same metro (min 5 prior years). Null when fewer than 5 prior years exist. (unit: Fahrenheit degree-days)
heat_wave_week	boolean	Derived: true when cdd_weekly is at or above the metro's own 90th percentile of weekly CDD over the full panel.
cold_snap_week	boolean	Derived: true when hdd_weekly is at or above the metro's own 90th percentile of weekly HDD over the full panel.
row_hash	string	Deterministic md5 of 'MDD\|<metro>\|<week_start>'; identical inputs hash identically.
