Regarding consistency of the species interpolation, I recall
cylindrical and spherical versions required some fixes (will appear in
the next release); cartesian version constraints the data by coarse
zones without making any distinction between variables.

In either case, I do not think that any interpolant we currently use
quarantees to produce smooth perfectly monotone data. Striping seems
odd, though.
