I think you’ll get more traction with this if you speed up the analysis. Probably easiest done by determining an interpolation grid, fill it with values, and return nearest neighbor as the result. Strictly speaking it could still be just as accurate as the uninterpolated approach, since when a raindrop falls, winds could place the drop on the ground some distance away from its release point.
