   * The NetCDF file format is **self-documented**, and the metadata of climate data files often follows the [[http://cfconventions.org/|CF (Climate and Forecast) Metadata Conventions]]
     * The files in the [[https://esgf-node.ipsl.upmc.fr/projects/esgf-ipsl/|CMIPn (n ≥ 5) database]] are written with the [[https://cmor.llnl.gov/|CMOR 3 library]] in order to make sure that they follow exactly the requested standards

+=== Some ways of working with NetCDF without programming ===
-  * [[http://cfconventions.org/|NetCDF CF (Climate and Forecast) Metadata Conventions]]: this will help you understand the information you get when you do a ''ncdump -h some_climate_data_file.nc''

+    * ''ncdump some_climate_data_file.nc'': dump the full content to text
-    * Using the [[http://unidata.github.io/netcdf4-python/|netCDF4]] module
+    * ''ncdump -h some_climate_data_file.nc'': only display the metadata
