Change default pole_method when source grid does bounds do not include the pole

[stephenworsley]

✨ Feature Request

When the source grid covers a limited band of latitudes, and especially when both bounds are the same side of the equator, it's likely to be inappropriate to extrapolate values that lie outside the source domain. The default behaviour for bilinear and nearest neighbour regridding is to use the esmpy ploe_method ALLAVG, however in such cases a it would be more appropriate to use the method NONE.

Still interested in this feature, any update on its status? Is it superceded by #375?

Solving #375 would allow you to resolve this issue yourself by passing the appropriate arguments. This would be done by PR: #396. I don't believe this would change the defaults yet, but it does provide the ability to pass arguments yourself. I think the decision to change the defaults is somewhat separate so this issue is worth keeping around, but do let me know if you feel the work in #396 would be sufficient for your purposes.
