Community Collaborative Rain, Hail and Snow Network (CoCoRHaS)
LSC Atmospheric Sciences Department and the Fairbanks Museum are jointly coordinating efforts in the northeast kingdom region of Vermont.
What is it?
CoCoRHaS is a network of volunteers taking precipitation observations across the country. Vermont’s participation is headed up by the National Weather Service office in Burlington, VT.
CoCoRaHS 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). The network originated with the Colorado Climate Center at Colorado State University in 1998 thanks in part to a flood in Fort Collins the prior year. In the years since, CoCoRaHS has expanded rapidly with over 12,000+ observers in thirty-nine states.
CoCoRaHS has several goals (as stated in the CoCoRHaS mission statement):
- providing accurate high-quality precipitation data for our many end users on a timely basis;
- increasing the density of precipitation data available throughout the country by encouraging volunteer weather observing;
- encouraging citizens to have fun participating in meteorological science and heightening their awareness about weather; and
- providing enrichment activities in water and weather resources for teachers, educators and the community at large to name a few.
How can I participate?
Volunteers will take measurements of precipitation from many different locations. These precipitation reports are then recorded on the official CoCoRHaS website.
The data are then displayed and organized for many of our end users to analyze and apply to daily situations ranging from water resource analysis and severe storm warnings to neighbors comparing how much rain fell in their backyards.
All that is required is that you measure precipitation at your home once a day and enter that information on the CoCoRHaS web site. Typically, this will be done in the morning such as before you would leave for work or go to school. It only takes a couple of minutes to complete each day. Once you are a member of the network you will be able to see your data on the national CoCoRHaS website, and compare your observations with other participants.
You may view a training document (PDF format) from the CoCoRaHS web site for more information about recording your data.
What do I need?
A rain gauge, an internet connection and an interest in the weather. You will need to sign up by filling out the on-line application form. Rain gauges can be purchased from Weather Your Way . If you are located in the Northeast Kingdom we at Lyndon State College can provide one to you for $20. Due to the need for consistency in measurements use of an approved rain gauge is required.
