What is CoCoRaHS?

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, our aim is to provide the highest quality data for natural resource, education and research applications. We currently operate in 49 states, with Minnesota completing the list on December 1st.

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.

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 our Web site and use our data.

What does CoCoRaHS hope to accomplish?

CoCoRaHS has the following goals:

  1. provide accurate high-quality precipitation data for our many end users on a timely basis
  2. increase the density of precipitation data available throughout the country by encouraging volunteer weather observing
  3. encourage citizens to have fun participating in meteorological science and heightening their awareness about weather
  4. provide enrichment activities in water and weather resources for teachers, educators and the community at large to name a few 

Who sponsors this network?

The National Oceanic and Atmospheric Administration (NOAA) is a major sponsor of CoCoRaHS. Other organizations have contributed either financially, and/or with supplies and equipment. Our list of sponsors continues to grow. Click here to visit our sponsor’s page. Many other organizations and individuals have pitched in time and resources to help keep the network up and running. We are grateful to all of you, as CoCoRaHS would not be possible without your help.

What are the benefits to 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.
