March Madness hits CoCoRaHS

CoCoRaHS has launched their 6th annual March Madness contest to recruit new observers from across the United States. What is CocoRaHS? It is an acronym for the Community Collaborative Rain, Hail and Snow Network.  CoCoRaHS is a unique, non-profit, community-based network of volunteers of all ages and backgrounds working together to measure and map precipitation (rain, hail and snow).   By using low-cost measurement tools, stressing training and education, and utilizing an interactive Web-site, their aim is to provide the highest quality data for natural resource, education and research applications. They are now in all fifty states. 

Welcome to the CoCoRaHS March Madness Page.  CoCoRaHS March Madness is our friendly recruiting contest between all 50 states to see who can recruit the most new volunteers during the 31 days of March.  

There is always a need for a greater number of observations, as the saying goes "the rain doesn't fall the same on all".  Due to the variability of precipitation, amounts measured can be quite different only a block or two away.  Help fill in the gaps by recruiting a friend or relative during our contest.  The more observations, the clearer the picture, the better the understanding of where it did and did not rain.

The contest is broken down into two categories: "Traditional Count" . . . the state that recruits the greatest number of new observers in March.  The second category is "Per Capita*" or population weighted . . . the state that recruits the greatest number of new observers per one million of it's total population.

The winning state in each category receives the "CoCoRaHS Cup" to keep and exhibit for a year until next year's contest (in the tradition of the NHL's Stanley Cup).  The cup usually travels around the state during the year, so check with your state coordinator for it's whereabouts.

Potential volunteeer observers from South Dakota, Minnesota, Iowa, or Nebraska are encouraged to go to and sign up!
