CoCoRaHS is an acronym for the Community Collaborative Rain, Hail and Snow Network.  CoCoRaHS is a unique, non-profit, community-based network of volunteers of all ages and backgrounds working together to measure and map precipitation (rain, hail and snow).   By using low-cost measurement tools, stressing training and education, and utilizing an interactive Web-site, our aim is to provide the highest quality data for natural resource, education and research applications. To learn more about why you should join CoCoRaHS and how your participation helps us, watch this video webinar.

Anyone can help observe! To learn more about the program and what is involved, how to join, etc., please view a recording of our CoCoRaHS training webinar.
