Datapoint is past its sell by and no longer supported. It has become increasingly unstable for our usage so we will need to look at moving away.

Its replacement is the "Weather Observations Website" or WOW - https://www.wow.metoffice.gov.uk/

Unfortunately I don't think we will be able to bundle API keys for WOW (in order to skip the registration step) so would require users to sign up.

The current tutorial extracts cloud cover from radar images which may or may not be available in WOW, if not we could use the "current weather" field. This would help us drop the Pillow dependency.

Note: Ideally the tutorial workflow would not have any additional dependencies beyond the regular cylc-flow dependencies.
