Short summary
This paper describes conservative interpolation on the sphere. A function is computed on one mesh from its values on another mesh so that the total mass is preserved, which is vital for climate modeling, and for second-order accuracy. This is done through a common refinement of the meshes, built in quasilinear time by tree sorting the mesh cells. It can be built into climate models for flexible I/O or coupling. Examples of commonly used meshes are given.
