We found a nice solution to this using @TomNicholas's Datatree

```python import xarray as xr import datatree

dt = datatree.open_datatree("AQUA_MODIS.20220809T182500.L2.OC.nc")

def fix_dimension_names(ds): if 'pixel_control_points' in ds.dims: ds = ds.swap_dims({'pixel_control_points': 'pixels_per_line'}) return ds

dt_fixed = dt.map_over_subtree(fix_dimension_names)

all_dsets = [subtree.ds for node, subtree in dt_fixed.items()] ds = xr.merge(all_dsets, combine_attrs="drop_conflicts") ds = ds.set_coords(['latitude', 'longitude'])

ds.chlor_a.plot(x="longitude", y="latitude", robust=True) ```
