If so, I would suggest using xESMF ([example here](https://xesmf.readthedocs.io/en/latest/notebooks/Curvilinear_grid.html)), since [xarray itself does not appear to support this type of interpolation yet](https://github.com/pydata/xarray/issues/2281). As an example, given the dimension names you currently have and expect in the output, your code could look something like the following:

```python
import xesmf as xe

# ...load data...

ds_xy_grid = ds_xy_grid.rename(latitude='lat', longitude='lon')
ds_out = xr.Dataset({'lat': (['lat'], np.linspace(44.77, 56.14, 421)),
                     'lon': (['lon'], np.linspace(2.976, 19.84, 461)})
regridder = xe.Regridder(ds_xy_grid, ds_out, 'bilinear')
ds_lonlat_grid = regridder(ds_xy_grid)
ds_lonlat_grid = ds_lonlat_grid.rename(lat='latitude', lon='longitude')
```

If someone else sees this: your line
`regridder = xe.Regridder(ds_xy_grid, ds_out)` is missing the method e.g. `regridder = xe.Regridder(ds_xy_grid, ds_out, 'bilinear')`","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,491719758
