Note: this PR builds a wights matrix and performs regridding with the expectation that the standard cube has the last two dimensions as the y and x dimension (see the change made in this commit 90130cc). This decision is made in order to maintain consistency with patterns established in existing regridders, e.g. the ordering of iris/lib/iris/analysis/_regrid.py Line 365 in e0850eb This cosistency is important so that further unification of regridding can take place without having to change the expected ordering of weights matrices associated with regridders. This decision is also in keeping with recomendations in CF conventions, see http:https://cfconventions.org/Data/cf-conventions/cf-conventions-1.10/cf-conventions.html#dimensions |
