The Community Collaborative Rain, Hail and Snow Network is a fun way for volunteers of all ages across the U.S. and Canada to help track rain, hail, and snow. By contributing daily precipitation observations using standardized, easy-to-use rain gauges, members become part of a nationwide network of citizen-scientists making a big impact on weather data used by the National Weather Service. It's a simple, hands-on way to learn about weather, help your community, and connect with others who love weather, too!
