Hello group: I have been gridding irregularly scattered data to a regular lat-lon grid near the south pole (the data that is, I'm not...). trigrid/triangulate with /sphere, or sph_scat, ought to be the answer but they don't produce good results: there appear to be rather arbitrary artifacts in the output. Anybody out there want to claim that sph_scat *does* work well for them? Near a pole? Near the south pole?
