NOAA Climate Data

Find NOAA weather stations in an area. Returns a list of weather stations with their IDs, names, coordinates, and active date ranges. Use the station IDs with get_climate_data. Args: state: Two-letter US state abbreviation (e.g. 'CA', 'NY'). county_fips: Five-digit county FIPS code (e.g. '36061' for Manhattan). dataset: Dataset ID to filter stations that have data in this dataset. Default is 'GHCND' (daily summaries). limit: Maximum number of stations to return (default 25, max 1000).

Get climate observations from NOAA Climate Data Online. Returns historical weather measurements such as temperature, precipitation, and snowfall. You must provide either a station_id or a FIPS code to identify the location, and a date range. Args: station_id: NOAA station identifier (e.g. 'GHCND:USW00094728' for Central Park). fips: FIPS code for county or state (e.g. '36' for New York state, '36061' for Manhattan). dataset: Dataset ID. Common values: 'GHCND' (daily summaries), 'GSOM' (monthly), 'GSOY' (annual), 'NORMAL_DLY' (daily normals). Default is 'GHCND'. start_date: Start date in YYYY-MM-DD format. Required for most datasets. end_date: End date in YYYY-MM-DD format. Required for most datasets. data_types: Comma-separated data type IDs to filter. Common types: TMAX (max temp), TMIN (min temp), TAVG (avg temp), PRCP (precipitation), SNOW (snowfall), SNWD (snow depth), AWND (avg wind speed). If omitted, all available types are returned. limit: Maximum number of records to return (default 100, max 1000).

Get 30-year climate normal values for a NOAA weather station. Climate normals are averages computed over the most recent 30-year period (currently 1991-2020). They represent typical conditions for a location and are useful for comparing current conditions to historical baselines. Args: station_id: NOAA station identifier (e.g. 'GHCND:USW00094728'). Use find_stations to look up station IDs. data_types: Comma-separated normal data type IDs to filter. Common types: DLY-TMAX-NORMAL (avg daily max temp), DLY-TMIN-NORMAL (avg daily min temp), DLY-TAVG-NORMAL (avg daily temp), DLY-PRCP-PCTALL-GE001HI (precip probability), MTD-PRCP-NORMAL (monthly precip), ANN-TMAX-NORMAL (annual max temp). If omitted, all available normals are returned.
