GSODR: Global Surface Summary of the Day ('GSOD') Weather Data Client
Provides automated downloading, parsing, cleaning, unit
    conversion and formatting of Global Surface Summary of the Day
    ('GSOD') weather data from the from the USA National Centers for
    Environmental Information ('NCEI').  Units are converted from from
    United States Customary System ('USCS') units to International System
    of Units ('SI').  Stations may be individually checked for number of
    missing days defined by the user, where stations with too many missing
    observations are omitted.  Only stations with valid reported latitude
    and longitude values are permitted in the final data.  Additional
    useful elements, saturation vapour pressure ('es'), actual vapour
    pressure ('ea') and relative humidity ('RH') are calculated from the
    original data using the improved August-Roche-Magnus approximation
    (Alduchov & Eskridge 1996) and included in the final data set.  The
    resulting metadata include station identification information,
    country, state, latitude, longitude, elevation, weather observations
    and associated flags.  For information on the 'GSOD' data from 'NCEI',
    please see the 'GSOD' 'readme.txt' file available from,
    <https://www1.ncdc.noaa.gov/pub/data/gsod/readme.txt>.
