@aidanheerdegen - thanks so much for posting this issue! I think a lot of people run into these sorts of problems, so it's useful to have an example on the issue tracker.

These problems can unfortunately be very hard to debug. If other developers can quickly reproduce your exact same error on their own systems, then we can try to dig deeper. However, I can't run the code you shared. If I paste it into a notebook, I get FileNotFoundError: [Errno 2] No such file or directory: b'/home/jovyan/cmip6-bot/2018/153/20180602090000-JPL-L4_GHRSST-SSTfnd-MUR-GLOB-v02.0-fv04.1.nc' Your example requires your files, which I don't have. I noticed some later examples point to a podaac opendap sever, commented out with the comment ```

This works fine

base_url = 'https://podaac-opendap.jpl.nasa.gov:443/opendap/allData/ghrsst/data/GDS2/L4/GLOB/JPL/MUR/v4.1/'

``` but I couldn't tell if I was supposed to run that part or not.

So unfortunately I have to ask you for some tweaks to your question. Could you either: 1. edit this example so that it points to an opendap server or other globally accessible endpoint on the internet? OR 1. replace the real data with synthetically generated data (e.g. use dask.random.random to create arrays instead of loading from disk)

Although 2 is a pain, it actually usually helps surface bugs by removing part of the I/O.

Thanks again for your contribution.
