I've uncovered another site where the average person (that's me and you) can help contribute to scientific research. This time, it's in the field of meteorology.
Colorado State University administers the Community Collaborative Rain, Hail and Snow Network (or CoCoRaHS for short) program. You can sign up to help measure and map rain, snow, and hail precipitation in your local community.
The team at CoCoRaHS then compiles the data into maps to track daily precipitation. The data is freely available to, and used by he 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.
Stay tuned as I identify more opportunities for folks like you and me to participate in research. If you know of any additional opportunities, post them in the comments below.
