The NCL 6.0.0 binaries and source code are hosted on the Earth System Grid (ESG) system.
If this is your first visit to the Earth System Grid, a short registration is required. To register, go to:
http://www.earthsystemgrid.org

Download source code or the appropriate binaries for your system
You can browse the different versions of NCL by going to http://www.earthsystemgrid.org and clicking on "NCL: NCAR Command Language" in the bottom center of the page. You don't need to login to browse the website.
When you find the version of NCL you're interested in, clicking on "Download files for this collection" will prompt you for your ESG login and password. You will then need to agree to the NCL Source Code License or the NCL Binary License before you can download any files.
There are two ways to download a file:
- You can click on the filename
in the left side of the table directly to download it to your current system.
- If you need to download a binary for a remote system, you can use "wget" to download one or more files. To use "wget", check one or more boxes to the left of the filename(s) you want to download. Click on "Download all selected files" and you will be given a chance to download a wget script for those files.
Depending on what you downloaded, read one or both of the following sections on installing NCL binaries or building NCL from source code.
