Thanks for this! I need to test is properly, but from a first pass of the code it looks great!

I know they're relatively small, but are you happy for me to upload the data start files to the S3 bucket, just to slim things down?

I think the plot titles/axes aren't quite working.

Since the plots are unique to each model, it would also be nice to include the model name somewhere in the title, if possible.
