Community Collaborative Rain, Hail and Snow Observations (CoCoRaHS)

Added By Infochimps
The National Weather Service (NWS) supports the Community Collaborative Rain, Hail and Snow (CoCoRaHS) 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, snow and hail). The network has over 6,500 observers in 26 states. Once trained, volunteers collect data using standardized, low cost measuring tools such as a 4-inch diameter high capacity rain gage, snow boards to measure snow, and aluminum foil-wrapped Styrofoam hail pads in some states. This site has been compiled by NWS and contains the results of the observations and data collection activities of these volunteers across a broad swath of the United States.
