Install NCL for post-processing

Install Conda

If you don’t already have “conda” installed on your system, then go to:

and select the appropriate “Python 2.7 64-bit bash installer” for your MacOSX or Linux system. Do not download the Python 3.x version! (We do not have a Windows version.)

Follow the instructions for installing miniconda. When the installation is finished, you can test it quickly by typing the following from a UNIX terminal window:

conda -V

This should echo something like “conda 4.3.13”.

Note: you can also use these conda instructions with an Anaconda distribution.

Install NCL using conda

We recommend that you install NCL under a conda “environment”, which we’ll call ncl_stable. You can call it whatever you want.

From a UNIX terminal window in sh/bash mode, type:

conda create -n ncl_stable -c conda-forge ncl=6.4.0
source activate ncl_stable

You will need to run the “source activate ncl_stable” command every time you log out and log back in.

Test the NCL installation

From a UNIX terminal window, type:

ncl -V
ng4ex xy05n -clean -W png

The first command should echo “6.4.0”. The second command should produce the following “xy05n.png” PNG image:

../_images/xy05n.png
