NOAA NCEI (Climate / Degree-Days)

No authnoaa-ncei

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

Methods (5)

  • getDegreeDays

    read

    Heating/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

    read

    Daily 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

    read

    Discover 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

    read

    List the NCEI dataset catalog (id, name, period of record, description).

    Paged with limit + offset.

  • getServiceInfo

    read

    Connector metadata: endpoints, degree-day dataTypes, unit conventions, and a reachability probe.

    No arguments. Useful for discovery.
