Changes in version 0.5.1 (2020-01-12)                  

  - Update the internal history_tbl object

  - Eliminate testthat tests that get data from the NOAA server to
    consistently pass CRAN checks

                 Changes in version 0.5.0 (2019-09-25)                  

  - Complete rewrite of package.

  - Package now has the main function get_met_data(), where
    get_station_metadata() and station_coverage() provide information on
    the station and which additional data fields they have reported on.

  - The get_met_data() function can bucketize observations so that even
    hourly observations are provided.

  - Instead of needing to provide a range of years, any vector of years
    can be provided to get_met_data().

  - The visibility parameter is now provided in the standard set of
    station observations.

  - A more reliable method of getting the local times for each station
    has been implemented.

  - Meteorological data files can be collected in a directory after
    download for later reuse.

  - Additional data fields, when requested, are processed much more
    quickly than in previous releases.

  - Tibbles are now returned instead of data frames.

  - A pkgdown site has been generated.

                  Changes in version 0.3 (2015-06-23)                   

  - Removes the get_tz_offset() function, the large shapefile object,
    and the dependencies on the lubridate, sp, and proj4 packages.

  - Greater use of dplyr functions to greatly increase processing speed.

  - Functions are resilient to missing years of data within year ranges
    provided.

                  Changes in version 0.2 (2015-06-17)                   

  - Added function get_ncdc_station_info() to obtain data frame of all
    known met stations, and, to filter list of stations by geographic
    bounding box and/or by years of available data.

  - Added function select_ncdc_station() to take the data frame produced
    by get_ncdc_station_info() and aid in obtaining a selection of a
    single station; the resulting identifier string can be passed to
    get_ncdc_station_data() to fetch data for the selected station.

                         Changes in version 0.1                         

  - Contains function get_ncdc_station_data() (to fetch data and create
    a data frame) and helper function get_tz_offset() (to determine time
    zone offset and correct times to local time).
