get_inventory

The <acronym>NCEI</acronym> maintains a document,
<a href="https://www1.ncdc.noaa.gov/pub/data/noaa/isd-inventory.txt">https://www1.ncdc.noaa.gov/pub/data/noaa/isd-inventory.txt</a>, which lists
the number of weather observations by station-year-month from the beginning
of the stations' records. This function retrieves that document and prints
an information header displaying the last update time with a data frame of
the inventory information for each station-year-month.

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,
