"""A Global Surface Summary of the Day (GSOD) Weather Data Client for R
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>."""
