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! Want to know more? Check out our CoCoRaHS links or contact your CoCoRaHS coordinator! Contact information is below.
Scientists everywhere! This includes people like the National Weather Service (NWS), the National Centers for Environmental Information (NCEI), universities studying the atmospheric and oceanic sciences, meteorologists on TV, and many more. For us at the weather service, CoCoRaHS observations are vital in helping us quality control the precipitation reports we get from weather stations since we cannot have weather stations everywhere. It can also clue us in to areas that may be in danger of experiencing areal or flash flooding. Want to know more about how CoCoRaHS observations are used? Click here!

Now, you are ready to start observing. There are several videos you can watch to learn how to measure rain, snow, and even hail. Click on one of the links below to learn more about measuring precipitation, hail, evapotranspiration, and recording your landscape’s current condition!
How much moisture are plants, trees, and other vegetation giving off to the atmosphere?
Is your landscape dry, normal, wet? These observations are incredibly helpful for determining drought conditions, above normal rainfall seasons, and fire weather forecasting.
