nearest_stations

Latitude expressed as decimal degrees (DD) (WGS84)

Longitude expressed as decimal degrees (DD) (WGS84)

Distance in kilometres from point for which stations are to
be returned.

distance

Given latitude and longitude values entered as decimal degrees (DD), this
function returns a list (atomic vector) of <acronym>STATION</acronym> values, which
can be used in <code><a rd-options="" href="/link/get_GSOD?package=GSODR&version=2.0.0" data-mini-rdoc="GSODR::get_GSOD">get_GSOD</a></code> to query for specific stations as an
argument in the <code>station</code> parameter of that function.

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 are calculated from the
original data 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,
