Average wind speed

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.

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.
