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') for use in R. 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 are
calculated from the original data and included in the final data set. The
resulting data include station identification information, state, country,
latitude, longitude, elevation, weather observations and associated flags.
Additional data are included with this R package: a list of elevation values
for stations between -60 and 60 degrees latitude derived from the Shuttle
Radar Topography Measuring Mission ('SRTM'). For information on the 'GSOD'
data from 'NCEI', please see the 'GSOD' 'readme.txt' file available from,
