Community Collaborative Rain, Hail and Snow (CoCoRaHS) Network
http://www.cocorahs.org/
CoCoRaHS is a grassroots volunteer network of backyard weather observers of
all ages and backgrounds working together to measure and map precipitation
(rain, hail and snow) in their local communities. By using low-cost
measurement tools, stressing training and education, and utilizing an
interactive Web-site, the aim of this program is to provide the highest
quality data for natural resource, education and research applications.
