NOAA NCEI Global Summary of the Day (GSOD)

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.
