The Cloud Collector’s Handbook works not just as a reference, but also as a game. You earn ‘cloud-collecting points’ for each cloud that you spot. These points are given on the reference pages on this site (on the bottom right of the image pages). The handbook also lists bonus points that can be earned when the cloud has a particular special feature.
The maximum score possible (including bonus points) is 2,000. If anyone manages to get all these points, and has taken photographs of the clouds in their collection to prove it, we will award them some fabulous prize.
We haven’t decided what it’ll be yet, as we’re confident this won’t happen any time soon.
