This gauge is heavy duty clear butyrate plastic and measures a full 11 inches of precipitation. The inner measuring tube has a capacity of 1 inch and is graduated to one hundredth of an inch. Rainfall exceeding 1.00 inch flows into the outer cylinder. Funnel and measuring tube are removed for collecting sleet and snow.
This precipitation gauge is the Official Gauge of the Community Collaborative Rain, Hail and Snow Network (CoCoRaHS) and can be purchased through the CoCoRaHS website. CoCoRaHS is a grassroots volunteer network of backyard weather observers of all ages and backgrounds working together to measure and map precipitation (rain, hail and snow) in their local communities. By using low-cost measurement tools, stressing training and education, and utilizing an interactive website, the aim is to provide the highest quality data for natural resource, education and research applications.
What is CoCoRaHS?
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). 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. CoCoRaHS is now in all fifty states.
Where did the CoCoRaHS Network originate?
The network originated with the Colorado Climate Center at Colorado State University in 1998 thanks in part to the Fort Collins flood a year prior. In the years since, CoCoRaHS now includes thousands of volunteers nationwide.
Who can participate?
This is a community project. Everyone can help, young, old, and in-between. The only requirements are an enthusiasm for watching and reporting weather conditions and a desire to learn more about how weather can effect and impact our lives.
What will our volunteer observers be doing?
Each time a rain, hail or snow storm crosses your area, volunteers take measurements of precipitation from as many locations as possible (see equipment). These precipitation reports are then recorded on the CoCoRaHS website.The data are then displayed and organized for many of their 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.
Who uses CoCoRaHS?
CoCoRaHS is used by a wide variety of organizations and individuals. The National Weather Service, other meteorologists, hydrologists, emergency managers, city utilities (water supply, water conservation, storm water), insurance adjusters, USDA, engineers, mosquito control, ranchers and farmers, outdoor & recreation interests, teachers, students, and neighbors in the community are just some examples of those who visit the website and use the data.
What do we hope to accomplish?
CoCoRaHS has several goals (as stated in the mission statement).
- provide accurate high-quality precipitation data for their 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
- providing enrichment activities in water and weather resources for teachers, educators and the community at large to name a few
Who is sponsoring this network?
The National Oceanic and Atmospheric Administration (NOAA) and the National Science Foundation (NSF) are major sponsors of CoCoRaHS. Other organizations have contributed either financially, and/or with supplies and equipment. The list of sponsors continues to grow. Many other organizations and individuals have pitched in time and resources to help keep the network up and running. Everyone at CoCoRaHS is grateful to all of you, as CoCoRaHS would not be possible without your help.
What benefits are there in volunteering?
One of the neat things about participating in this network is coming away with the feeling that you have made an important contribution that helps others. By providing your daily observation, you help to fill in a piece of the weather puzzle that affects many across your area in one way or another. You also will have the chance to make some new friends as you do something important and learn some new things along the way. In some areas, activities are organized for network participants including training sessions, field trips, special speakers, picnics, pot-luck dinners, and photography contests just to name a few.
