ease_1.ncl:
This script illustrates how to create contours of an EASE grid. The
first frame is a contour plot only, and the second frame overlays the
contours on a northern hemisphere polar stereographic map. Drawing the
contours only is much quicker, and is good for quick debugging
purposes.

EASE Grids
This page shows how to use NCL to analyze EASE (Equal-Area Scalable
Earth) grids (obtained from the National
Snow and Ice Data Center).

In order to generate contours over a map from this kind of grid, you must set the resource trGridType to "TriangularMesh", and make sure you have the special 2D lat2d and lon2d attributes attached to the data.
