We can either 1) add a note on the notebooks to let the the user know Python3 (ipykernel) is the kernel of xcdat_notebook by default or 2) add the extra step to register the kernel in all of the notebooks, which is necessary if the tries to use the notebooks through a Jupyter instance invoked elsewhere and not xcdat_notebook.
Also we should make sure the conda env setup instructions are identical across notebooks.
