Monthly heating and cooling degree days (GSOM dataset) from real representative weather stations across 5 U.S. climate regions. Federal-produced-tier data targets a CC0 license per NOAA's own Open Data Policy - no attribution strictly required, though our site credits it anyway.
| Region | Climate region id | Station |
|---|---|---|
| Northeast | CLIM:101 | Aberdeen Phillips Field, MD |
| West | CLIM:109 | Oakland International Airport, CA |
| South | CLIM:106 | San Antonio International Airport, TX |
| Central | CLIM:103 | St. Louis Lambert International Airport, MO |
| Southeast | CLIM:104 | Greensboro Piedmont Triad International Airport, NC |
Raw degree-day series are not yet exposed via /v1/series
(that endpoint currently serves EIA data only) - the
weather demand anomaly factor
built from this data is already queryable via /v1/factors.
