What is CoCoRaHS?

CoCoRaHS stands 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 Website the aim is to provide the highest quality data for natural resource, education and research applications. There are CoCoRaHS observers in all 50 states. There are even observers in Puerto Rico and Canada! Reports from CoCoRaHS observers are used by the National Weather Service, the National Centers for Environmental Information, engineers, farmers, teachers, and many others. This data becomes a part of the climate historical record to help us better understand past events. Anyone can become an observer! Interested in becoming one? Great! Follow the steps below!
