Community Collaborative Rain, Hail, Snow (CoCoRaHS)

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. They are now in all fifty states.

The CoCoRaHS web page provides the ability for observers to see their observations mapped out in "real time", as well as providing a wealth of information for data users. CoCoRaHS is used by a wide variety of organizations and individuals including the National Weather Service, other meteorologists, hydrologists, emergency managers, city utilities (water supply, water conservation, storm water), insurance adjusters, USDA, engineers, mosquito control, ranchers and farmers, outdoor & recreation interests, teachers, students, and neighbors in the community.
