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>.
