get_inventory

<p>The NCEI maintains a document,
&lt;ftp://ftp.ncdc.noaa.gov/pub/data/noaa/isd-inventory.txt&gt;, which shows the
number of weather observations by station-year-month from the beginning of
the stations' records.  This function retrieves that document, prints the
header to display the last update time and returns a data frame of the
inventory information for each station-year-month.</p>

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.  Data may be automatically saved
to disk. File output may be returned as a comma-separated values (CSV) or
GeoPackage (GPKG) file.  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, <http://www1.ncdc.noaa.gov/pub/data/gsod/readme.txt>.
