Yes, `pad` solves the hard part of periodic boundary conditions -- we should just need to do a bit of book-keeping on the xarray side.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,356698348

I wonder if we should consider calling this `xarray.differentiate` instead of `xarray.gradient`. I think the NumPy function is poorly named for differentiating along a single axis at once.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,356698348
