Short summary
The latitude-longitude grid is the most widely used global coordinate system for various purposes but its polar problems hinder its applications. Spherical multiple-cell (SMC) grid is developed to tackle the problems and uses unstructured technique and quad-tree like mesh refinement. It uses a fixed reference direction to define vector components near the pole for improved polar performance. It has been used in ocean surface wave models and possible applications in other models are explored.
