What you can ask
- “What does NOAA NCEI (Climate / Degree-Days) have for the area or asset I'm working on?”
- “Pull the most recent NOAA NCEI (Climate / Degree-Days) records and put them in a table.”
- “What does NOAA NCEI (Climate / Degree-Days) cover, and how fresh is the data?”
About this source
NOAA NCEI historical climate data via the keyless Access Data Service: - Daily summaries (GHCN-Daily): TMAX/TMIN/PRCP by station + date range - Climate normals (1991-2020): annual, seasonal, monthly heating/cooling degree-days (HDD/CDD) - Station + dataset discovery (by bbox or id) CRITICAL USAGE RULES: 1. No auth — keyless /access/services path, NOT the token-gated CDO v2 API 2. Degree-days (HDD/CDD) drive heating-oil / natural-gas / power demand — getDegreeDays() weather-normalizes production/load and models seasonal gas demand 3. Daily temps scaled tenths-°C→°C, precip tenths-mm→mm; degree-days are whole, °F base (65°F) 4. searchStations() (bbox order north,west,south,east) finds station ids for the data methods

getDegreeDays
readHeating/cooling degree-day climate normals (HDD/CDD) by station — annual, seasonal, or monthly.
Whole degree-days, °F base (65°F). period: annual|seasonal|monthly.
getDailySummaries
readDaily climate summaries (TMAX/TMIN/PRCP) by station + date range, scaled to °C / mm.
Temps tenths-°C→°C, precip tenths-mm→mm. Dates YYYY-MM-DD.
searchStations
readDiscover GHCN stations by bounding box or id; returns id, coordinates, and period of record.
bbox order: north,west,south,east. Page with limit (max 1000) + offset.
listDatasets
readList the NCEI dataset catalog (id, name, period of record, description).
Paged with limit + offset.
getServiceInfo
readConnector metadata: endpoints, degree-day dataTypes, unit conventions, and a reachability probe.
No arguments. Useful for discovery.
