11 April 2012In a new NCAR initiative to promote transparent and easy access to scientific resources, NCL has been assigned a Digital Object Identifier (DOI). DOIs are persistent identifiers 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.
Please cite NCL in your publications using the following citation (line breaks were added for clarification but the citation should be on one line):
The NCAR Command Language (Version 6.0.0) [Software]. (2012). Boulder, Colorado: UCAR/NCAR/CISL/VETS. http://dx.doi.org/10.5065/D6WD3XH5
You will need to update the NCL version and year as appropriate.
For more information about DOIs, see http://www.doi.org and http://en.wikipedia.org/wiki/Digital_object_identifier.

28 Sep 2009Using NCL with VAPOR to visualize WRF data
As a result of a collaboration between the NCL and VAPOR teams at NCAR, users can now display NCL plots of WRF output in 3D, combined with satellite images, political boundaries and other images from Web mapping services. There's a short tutorial to help users use this feature.
We would like to hear user feedback: Is this feature useful? Is it easy enough to use? Is the documentation OK? Please send your comments to ncl-talk.
21 Sep 2009The old NCL web site has been removed. The http://archive.ncl.ucar.edu/ URL will no longer work.
27 Jul 2009
We're excited to announce a new design for the NCL website!
Some new features that we think you'll like are:
- Cleaner look.
- Pull-down menus allow quicker access to sub pages.
- Better organization of the navigation bars.
- More useful information on main page (announcements, upcoming release, workshops).
The structure of the new web site should be almost identical to the previous web site, so most bookmarks should still work.
Many thanks go to Adam Phillips of NCAR/CGD, who provides scientific and programming support for both NCL and the Community Atmosphere Model (CAM). He designed this web site in his spare time.
The previous NCL web site is still available, should you wish to compare. It will stay up until the end of August: http://archive.ncl.ucar.edu/
We are interested in getting your feedback.
You can send comments to Adam and Mary. If you want to start a dialog on ncl-talk, that's fine too. Please be respectful of the amount of email that goes through this list, and not overwhelm it with minor issues.
