Functions for downloading,
    calibrating, and analyzing atmospheric isotope data bundled
    into the eddy covariance data products of the National Ecological
    Observatory Network (NEON) <https://www.neonscience.org>. 
    Calibration tools are provided for carbon and water isotope products.
    Carbon isotope calibration details are found in Fiorella et al. (2021)
    <doi:10.1029/2020JG005862>, and the readme 
    file at <https://github.com/lanl/NEONiso>. Tools for calibrating water 
    isotope products have been added as of 0.6.0, but have known deficiencies
    and should be considered very experimental currently.

NEON observational data are provided via the NEON Data Portal <https://www.neonscience.org> 
  and NEON API, and can be downloaded and reformatted by the 'neonUtilities' package. NEON observational data 
  (human-observed measurements, and analyses derived from human-collected samples, such as tree diameters and 
  algal chemistry) are published in a format consisting of one or more tabular data files. This package provides 
  tools for performing common operations on NEON observational data, including checking for duplicates and 
  joining tables.

Downloading and organizing plant presence and percent cover data from the National Ecological Observatory Network <https://www.neonscience.org>.

The National Ecological Observatory Network (NEON) provides access
  to its numerous data products through its REST API, 
  <https://data.neonscience.org/data-api/>. This package provides a
  high-level user interface for downloading and storing NEON data products.
  Unlike 'neonUtilities', this package will avoid repeated downloading,
  provides persistent storage, and improves performance.  'neonstore' can also
  construct a local 'duckdb' database of stacked tables, making it possible
  to work with tables that are far to big to fit into memory.

NEON data packages can be accessed through the NEON Data Portal <https://www.neonscience.org>
    or through the NEON Data API (see <https://data.neonscience.org/data-api> for documentation). Data delivered from
    the Data Portal are provided as monthly zip files packaged within a parent zip file, while individual files
    can be accessed from the API. This package provides tools that aid in discovering, downloading, and reformatting 
    data prior to use in analyses. This includes downloading data via the API, merging data tables by type, and 
    converting formats. For more information, see the readme file at <https://github.com/NEONScience/NEON-utilities>.
