NOAA datasets

NOAA datasets use several independent services. Choose a dataset below for its query requirements, file format, and scientific limits. All currently supported NOAA access is anonymous.

See the generated catalog for status, capabilities, endpoints, and versions. Historical endpoint probes and candidate sources are in service research notes.

Geographic queries use bounding rectangles, which can include stations outside a state's actual boundary. See place lookup. Use explicit station IDs when exact selection matters. NOAA data is generally a U.S. Government work in the public domain; check each source's license.
