GriddedData2SphericalDistance

Compute the spherical distance on the unit sphere in radians between all point pairs of two grids. The spherical distance is computed by \begin{equation} \psi_{12} = \arccos(\M n_1 \cdot \M n_2), \end{equation}where $\M n_i$ is the (normalized) position. This implies that all points are projected onto the unit sphere.
