How to cite the NCAR Command Language (NCL)

NCL has a Digital Object Identifier (DOI), which is a persistent identifier for web-based resources. The NCL DOI, when used in URL form, http://dx.doi.org/10.5065/D6WD3XH5, provides a persistent link to the NCL web page. The benefit of DOIs is that they are widely accepted by academic publishers as citable locators for scholarly objects.

If you author a paper that involves data analysis with NCL, or visualizations created by NCL, we would like to ask you to please cite NCL. This helps us better understand the impact of the software on the scientific community, which in turns helps us maintain support for the effort.

You can cite NCL using the following citation (line breaks were added for clarification but the citation should be on one line):

  The NCAR Command Language (Version 6.4.0) [Software]. (2017). 
  Boulder, Colorado: UCAR/NCAR/CISL/TDD. http://dx.doi.org/10.5065/D6WD3XH5

You will need to update the NCL version and year as appropriate.
