This paper describes how to solve the incompressible Euler equations in spherical coordinates on a staggered grid defined on the sphere. The goal of this method is to accurately model fluid behavior regardless of the underlying grid definition (i.e, the result should be grid-agnostic). In particular, we invent and implement several techniques to manage polar singularities that emerge in the spherical coordinate representation of the incompressible Euler equations.
