I first worked with the [API](http://xarray.pydata.org/en/stable/generated/xarray.Dataset.interp.html#xarray.Dataset.interp)
Clearly documented in the [link](http://xarray.pydata.org/en/latest/interpolation.html) you provided.

I noticed the attrs get lost after orthogonal interpolation (see the first/second plots of `arr` in [mybinder](https://mybinder.org/v2/gh/gwin-zegal/interp/master?filepath=interpolation.ipynb), I might open a new issue for that

had a deeper look at `DataArray.interp` and it computes a new DataArray with new coords given by the dict. I first thought i'll get a 1D array which is not the case (this is often the behavior I want). I then compared first 10_000 interpolations on sdf against 100_000_000 in xarray! It explains the gap.

Updated my comparison with the same behavior with scipy and sdf in a jupyter notebook on [mybinder](https://mybinder.org/v2/gh/gwin-zegal/interp/master?filepath=interpolation.ipynb)

It seems everything's well with xarray.

Extrapolation (linear first) would be a good feature too, I put an example at the end of the notebook about sdf interpolation/extrapolation possibilites (work for nd-arrays of dim 32 as with numpy) ","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,330918967
