Volcanoes are a tricky one. There are a few volcanic eruptions in historical data, but it's unclear if this is enough to predict reasonably well how such future eruptions (especially at unseen locations) will affect the weather. Would be fun to look at some events and see what the model is doing. Thanks for the suggestion!

Re where do we start. A lot of organisations across different sectors need better weather predictions or simulations that depend on weather. Measuring the skill of such models is a relatively standard procedure and people can check the numbers.
