Interpolation over derived coordinates

[duncanwp]

None of the interpolation interfaces appear to support interpolation over hybrid (derived) coordinates. However I've been looking at interpolation of a single point on a cube with hybrid height and it seems to be fairly straightforward to first ask for a vertical column using any of the interpolation methods available, and subsequently ask for an (altitude) interpolation over that column.

Could this be built into the iris interpolation routines to save the overhead of these two seperate calls?

Yes - that would be excellent. Though I'm a little uncertain of the difficulties in doing so. 👍

This is still something that would be nice to have

I'd still be interested if we can get it implemented!
