CoCoRaHS members know a lot about rain, hail, and snow, but have you ever wondered about the wonderful, sometimes mysterious, world of fog and dew?  In this presentation, we will talk about how fog and dew form and how they interact with natural and built environments.  What is the difference between a cloud and fog? How do plants, animals, and humans use water from fog or dew in dry climates? How do fog and dew enhance pollutant deposition to sensitive ecosystems? How does fog affect transportation safety? How do fog and dew intertwine with human culture? Join us for a wide-ranging discussion of these other forms of atmospheric water.
