COCORAHS MARCH MADNESS

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 at any certain time.

The CoCoRaHS Cup -  Does it look like a sterling silver rain gauge?  Tiffany's would be proud.


*Per Capita Scoring - For each new volunteer who signs-up, the state will be given a percentage of "one point" based on the states total population (potential volunteer pool).  This will give those states with sparser populations an equal chance.  States with smaller populations will receive a larger point value for a new volunteer compared to those with larger populations (For each new volunteer Wyoming will receive 1.77 points based on their population of 563,626 residents, whereas California who will receive 0.03 points with their population of 37,253,956 residents).  These point values are based on "new stations per million residents" which is derived from the 2010 estimated population information (http://en.wikipedia.org/wiki/List_of_U.S._states_by_population).
