7 tools for working with the NOAA Climate Data Online (CDO) API v2:

Tool	Description
`noaa_list_datasets`	List available CDO datasets with IDs, names, and temporal coverage
`noaa_list_data_categories`	List data category groups (Temperature, Precipitation, Wind, etc.)
`noaa_list_data_types`	List specific measurement labels (TMAX, TMIN, PRCP, SNOW, etc.) by dataset or category
`noaa_find_locations`	Search geographic locations by category (states, cities, counties, zip codes, climate regions)
`noaa_find_stations`	Search weather stations by location, bounding box, dataset, and data type
`noaa_get_station`	Fetch full metadata for a single station by ID
`noaa_fetch_data`	Fetch historical observation records for a dataset and date range

List all available NOAA CDO datasets — approximately 11 in total.

Returns dataset IDs, names, data coverage fraction, and temporal range
No required parameters — returns everything by default
Optionally filter by data type, location, station, or date range
Common datasets: GHCND (daily, 1763–present), GSOM (monthly), GSOY (annual), NORMAL_DLY/MLY/ANN/HLY (1981–2010 climate normals)
Start here to orient before calling noaa_fetch_data

List data category groups that organize related measurement types.

~41 categories including Temperature, Precipitation, Wind, Pressure, Sunshine, Sky cover, Weather Type
Optionally filter by dataset, location, station, or date range
Use before noaa_list_data_types to narrow by measurement domain

List specific measurement labels for a dataset or category.

Hundreds of data types across all datasets
Filter by dataset (e.g., GHCND) or category (e.g., TEMP) to narrow results
Common GHCND types: TMAX (max temperature), TMIN (min temperature), PRCP (precipitation), SNOW (snowfall), SNWD (snow depth), AWND (average wind speed)
Returns ID, name, coverage fraction, and date range per type

Search geographic locations by category.
