Description

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>.
