What is CoCoRaHS?
The Community Collaborative Rain, Hail, & Snow Network (CoCoRaHS) is a nationwide volunteer reporting network that provides precipitation measurements for natural resource, education and research applications. The National Weather Service uses CoCoRaHS precipitation data daily in river forecast models, flood and drought forecasts, and precipitation and snowfall maps and tables.
CoCoRaHS (pronounced co-co-raws) allows observers to share their precipitation measurements via the Internet, which can be used by agencies who need accurate, real-time precipitation data for various purposes. The only equipment needed to join CoCoRaHS is a standard 4" diameter plastic rain gauge and access to the Internet to enter reports. Observers can report precipitation daily or only on days when they are able to take measurements. CoCoRaHS observers can also send real-time severe weather reports to the National Weather Service (NWS); including hail size, flooding, storm damage, and excessive rainfall, which greatly assist meteorologists in determining the impact of storms on local communities.
Due to Wyoming's expansiveness, the CoCoRaHS network is an invaluable tool for the NWS and other state and federal agencies to help fill-in the gaps due to a lack of available observation sites. This shortfall is mitigated by volunteers from across the state. Precipitation, in both winter and summer, can have wide ranging values. The more people reporting these data can greatly assist the NWS in providing better forecasts and warnings. Volunteers are welcome from across the state, and we always need more people to join.
This is a community project. Everyone can help: young, old and in-between! Click here to sign up as a CoCoRaHS Volunteer Observer.
