Questions this answers
4 · best fit firstOpen station-day rows supply dated mean wind, maximum sustained wind, and maximum gust with units and station identity, supporting climatology under distance/completeness rules.
Station-day minimum temperature and provenance support thresholded freeze-day frequency and seasonality. Daily summaries bound rather than measure subdaily freeze duration.
NOAA NCEI GSOD supplies public daily station summaries keyed by STATION and DATE, including temperature, precipitation, snow depth, mean and maximum sustained wind, maximum gust, and daily weather-occurrence flags. Station, date, and one-day aggregation pin the answer; the product does not establish an intraday timestamp.
Station-day snow depth and snow or ice occurrence flags provide useful snow-presence and depth climatology with station and date pins, but do not establish snowfall amount.
