Minimum temperature

Integrated daily land-station climate dataset from more than 100,000 stations in 180 countries and territories. It supplies station-day temperature, precipitation, snowfall, snow depth, wind, weather-type, and per-datum attribute fields. NOAA provides station files, an all-stations archive, CDO, and the NCEI Access Data Service. Some non-U.S. WMO-contributed data may have commercial-use or re-export restrictions.

Existing daily station-summary Source derived from ISD observations. Preserve its API and bulk-file access, add exact GSOD scalar fields beyond the existing minimum-temperature and precipitation fields, and clarify that wind is emitted in knots rather than converted mph. Some non-U.S. WMO-contributed data may have commercial-use or re-export restrictions.

A separately named Version 2 station summary product publishing hourly, daily, and monthly observations in station-year CSV files and monthly summary forms. It is derived from NCEI station datasets but has its own documented 125-column CSV schema, metric bulk files, U.S.-focused station coverage with limited U.S. Air Force locations abroad, and standing per-station/year plus all-station archive access.

Commercial global Timeline API for buyer-selected addresses, partial addresses, coordinates, or US ZIP codes and date ranges. It returns historical daily and hourly records in JSON/CSV; paid plans document 50+ years of history, commercial use, downloads, API access, and multi-location request allowances.

Commercial version-2.0.1 API returning daily or hourly NOAA-reanalysis history for arbitrary latitude/longitude points, postal codes, DMAs, and OnPoint identifiers. Coverage is every landmass worldwide and up to 200 miles offshore; the public specification does not pin the earliest retained date.
