NCL is a scripting language designed for the analysis and visualization of geoscientific data. It supports a wide range of data formats, has hundreds of computational functions that are tailored for climate science, and its visualizations are publication quality and highly customizable. As of 2020, NCL is in maintenance mode, meaning that NSF NCAR will not add new features to the NCL language or function library.
