CoCoRaHS March Madness is Underway - We Need Your Help! 



CoCoRaHS -- National Precipitation Monitoring Network Urgently Needs Additional Volunteers to Measure Precipitation in Their Own Backyards!

Ever wonder how much rain fell out of the storm that just passed overhead? Did your mother-in-law on the other side of town get just as wet? Why is the airport so much drier than my house? Wonder no longer.
Now, in your very neighborhood, volunteers of all ages and backgrounds are measuring precipitation in their own backyards as part of CoCoRaHS - the Community Collaborative Rain, Hail and Snow Network which as grown to over 15,000 volunteer observers covering every state of the country. More volunteers are urgently needed! It’s fun, easy and only takes five minutes a day.
“We are pleased that this simple backyard monitoring program has become so popular,” said Nolan Doesken, the Colorado State Climatologist at the Colorado Climate Center in Fort Collins, Colorado. “These volunteers are providing scientists around the country with excellent precipitation and hail monitoring statistics for tracking weather patterns and water supplies.”
The CoCoRaHS network engages volunteers of all ages from grade schoolers on up to folks in their 90’s to document the size, intensity, duration and patterns of precipitation by taking simple measurements in their own backyards. Volunteers only need a cylindrical rain gauge, some training and an interest in weather to participate in the program. The specific rain gauges that CoCoRaHS uses are available from several distributors on the network’s website ( for $25 plus shipping. The site also offers on-line training.
Data from CoCoRaHS volunteers are now being routinely viewed and used by many professions and organizations including the National Weather Service, meteorologists, hydrologists, emergency managers, city utilities, insurance adjusters, agribusinesses, engineers, science teachers and many more. Data are used for many applications such as water resource planning, severe storm warnings, teaching earth science, predicting crop yields and for assessing hail damage.
During the month of March 2010, CoCoRaHS is running it’s friendly annual competition among states --“CoCoRaHS March Madness” to see how many new observers can be recruited in each state. If you have a relative, friend or neighbor who is interested in weather, this is a great time to have them become part of the program.
