 Note: The //long_name// attribute is defined to contain a long descriptive name of the variable which may, for example, be used for labelling plots. The //standard_name// attribute is the name used to identify the physical quantity and must be taken from the [[https://cfconventions.org/standard-names.html|CF standard name table]]. Parameters with no suitable standard_name should be described using the long_name attribute only. Note: The //long_name// attribute is defined to contain a long descriptive name of the variable which may, for example, be used for labelling plots.

 +  * [[https://downloads.unidata.ucar.edu/netcdf/|NetCDF library software]]: //ncdump// can convert a netCDF binary file to CDL text.
 +  * [[https://www.giss.nasa.gov/tools/panoply/|Panoply]] and [[http://cirrus.ucsd.edu/~pierce/software/ncview/index.html|Ncview]] are great visualisation tools.
 +  * [[http://nco.sourceforge.net/|NCO]] is a command-line toolkit for manipulating netCDF files: //ncatted// and //ncrename// are specifically useful for editing metadata on the fly.
