Welcome to CoCoRaHS!
We are seeking Ohio residents to participate in a weather spotter network called CoCoRaHS, the Community Collaborative Rain, Hail, and Snow Network. The precipitation data collected by CoCoRaHS volunteers helps the National Weather Service verify and improve its forecasts and university researchers can use the data to advance the science of Meteorology.
Volunteers are required to complete a short training to learn how to make accurate precipitation measurements. There are virtual training courses each spring or you can go through the training slides and videos on the left hand of the CoCoRaHS website under resources.
Upcoming CoCoRaHS Training Classes in Ohio:
CoCoRaHS on-line training animations are available through the CoCoRaHS Web site. We think you'll enjoy them. They are very informative and entertaining. In order to measure rainfall, a rain gauge is required, and volunteers need to purchase one if they do not have one. CoCoRaHS rain gauges can be purchased through various vendors. Volunteers make daily precipitation measurements and enter precipitation data through the CoCoRaHS web site.
A table containing data collected by CoCoRaHS volunteers is posted daily on National Weather Service web sites. For more information on becoming volunteer, visit the CoCoRaHS web site, or contact your state or regional coordinator.
