How To Install ncl on CentOS 8
ncl is NCAR Command Language and NCAR Graphics
Introduction
In this tutorial we learn how to install ncl on CentOS 8.
What is ncl
NCAR Command Language (NCL) is an interpreted language designed specifically for scientific data processing and visualization. Portable, robust, and free, NCL supports netCDF3/4, GRIB1/2, HDF-SDS, HDF4-EOS, binary, shapefiles, and ASCII files. Numerous analysis functions are built-in. High quality graphics are easily created and customized with hundreds of graphic resources. Many example scripts and their corresponding graphics are available.
We can use yum or dnf to install ncl on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install ncl.
Install ncl on CentOS 8 Using dnf
Update yum database with dnf using the following command.
sudo dnf makecache --refresh
