I have a netcdf with polar stereographic variable. How can I extract data from these files?

In geometry, the stereographic projection is a particular mapping (function) that projects a sphere onto a plane. The projection is defined on the entire sphere, except at one point: the projection point. Where it is defined, the mapping is smooth and bijective. It is conformal, meaning that it preserves angles at which curves meet. It is neither isometric nor area-preserving: that is, it preserves neither distances nor the areas of figures. Ref

You can use any netcdf files by using Open NC File tool. The Open NC File tool is a unique tool for extracting data from any netcdf files. You will not need any knowledge about polar stereographic and the tool will reprojection the polar stereographic system to regular lat/lon. In fact, you should enter the regular lat/lon in decimal (or degree/minutes/second) or UTM system then if your coordinate system is polar stereographic, the tool reproject it.
