Not yet.
`interp()` only works on N-dimensional regular grid.
Under the hood, we are just using `scipy.interpolate.interp1d` and `interpn`.

I am happy to see curvilinear interpolation in xarray if we could find a good general API for N-dimensional array.
Do you have any proposal?

For curvilinear interpolation, we may have some arbitrariness,
e.g. 
```python
dr_out = dr.interp(xc=lon)
```
the resultant dimension is not well determined. Maybe we need some limitation for the arguments.
