I guess you could edit https://satpy.readthedocs.io/en/latest/api/satpy.demo.html#satpy.demo.get_hurricane_florence_abi

to get the data needed for this example

Thanks for the issue. You wouldn't even need to edit the code, just pass different kwargs to get_hurricane_florence_abi to only get C01-C03 and get 100 frames instead:
