What AI says about CoCoRaHS

CoCoRaHS is a grassroots volunteer network of backyard weather observers who measure and map precipitation (rain, hail, and snow) in local communities. It uses low-cost measurement tools, training, and an interactive website that shows observations in real time and supports natural resource, education, and research applications. Since 1998, the network has grown to more than 27,500 active observers across the United States, Canada, Puerto Rico, the U.S. Virgin Islands, Guam, and the Bahamas.
