CoCoRaHS Network


CoCoRaHS "Precipitation Absurdity!" 2024






Residents of both Georgia and South Carolina can now participate as volunteer weather observers by measuring rain, snow and hail through the CoCoRaHS Program.

So, what is CoCoRaHS?

CoCoRaHS stands for Community Collaborative Rain, Hail and Snow Network. CoCoRaHS began with the Colorado Climate Center at Colorado State University in 1998 in response to the damaging Fort Collins flood in 1997.

The CoCoRaHS network is looking for enthusiastic volunteers to report rainfall, snowfall and hail information. Observers can be individuals, who take readings in their backyard, at schools, their places of work, at golf courses and local farmers. The rainfall measurements are made using high quality 4 inch rain gauges. The information is used by a wide variety of organizations such as:  The National Weather Service; Television Meteorologist; Farmers; Hydrologist; Researchers; Emergency Managers; Water Resource Managers and many others. Become a piece of the meteorological puzzle and join volunteers from the United State...Canada...Puerto Rico...U.S. Virgin Island and Bahamas. It's easy to join and only takes less than 5 minutes a day, so become an observer it's a wonderful way to help your community and learn about this wonderful natural resource that falls from the sky. To make entering your daily data even easier there is an app for Android and iPhone.

Remember: "Every Drop Counts" & "The Rain Doesn't Fall The Same On All"
