@jthielen Something like this?

```python import xarray as xr import cupy as cp

@xr.register_dataset_accessor("cupy") class CupyAccessor: def to_cupy(self): """Convert all data arrays to cupy."""

    for var in self.data_vars: 
        self.data_vars[var].data = cp.asarray(self.data_vars[var].data)

    return self

```

Which would then be used like this.

```python import xarray as xr import cupy as cp

ds = xr.open_mfdataset("/path/to/files/*.nc") gds = ds.cupy.to_cupy() ```
