The Cloudspotting notebook comes with several nice features to help get your head into the clouds. Guides to cloud and weather symbols (who knew meteorologists use secret codes?) A list of cloud nomenclature terms (aha! cirrus clouds are named for their curls.) A cloud identification chart, so you can immediately start recognizing the clouds overhead. The pages are formatted so you can document new cloud types, record all the storms you've chased, or simply jot notes while you're enjoying the weather. 48 pages 3.5" x 5".
