The Community Collaborative Rain, Hail and Snow (CoCoRaHS) network is a unique, nonprofit, community-based network of volunteers of all ages and backgrounds working together to measure and map precipitation including rain, hail and snow.
CoCoRaHS originated with the Colorado Climate Center at Colorado State University in 1998 in response to the Fort Collins flood of 1997. Today, CoCoRaHS has over 6,500 observers in 27 states with a potential goal of 20,000 by 2010 as more states are added. Nine additional states will become active in 2008. The Louisiana project was made possible via a collaborative effort between Colorado State, Louisiana State University, University of Louisiana at Monroe, Delta Community College, and the National Weather Service.
Everyone is invited to participate. The only requirements are an enthusiasm for watching and reporting weather conditions using a standard 4" scientific rain gauge (which can be purchased for about $29).
Each time a rain, hail, or snow storm crosses the area, volunteers will measure and record precipitation, then submit the data to the CoCoRaHS website. This data is plotted with other reporting stations for analysis by a variety of organizations from the National Weather Service, hydrologists, emergency managers, city utilities, insurance adjusters, mosquito control, farmers, teachers, students, and those interested in precipitation data.
