But you could do this with `apply_ufunc` instead, e.g., something like:
```python
def interptotarget(y, x, target):
return interp1d(x, y)(target)
target = xr.DataArray([213.5, 213.6], dims='target_lon')
xr.apply_ufunc(interptotarget, airtemps, airtemps.lon, target,
input_core_dims=[['lon'], ['lon'], ['target_lon']],
output_core_dims=[['target_lon']]
).assign_coords(target_lon=target)
```
results in
```
Dimensions: (lat: 25, target_lon: 2, time: 2920)
Coordinates:
* lat (lat) float32 75.0 72.5 70.0 67.5 65.0 ... 22.5 20.0 17.5 15.0
* time (time) datetime64[ns] 2013-01-01 ... 2014-12-31T18:00:00
* target_lon (target_lon) float64 213.5 213.6
