Welcome to CoCoRaHS in Illinois!
CoCoRaHS observers provide a great service to the community by providing information on precipitation across the state. This information is used by scientists, community officials, farmers, emergency managers, and your friends and neighbors to see where daily precipitation has occurred in Illinois. Anyone with an interest in the weather or the environment is welcome to participate.
What Do I Need
The only requirements for participation are an enthusiasm for watching and reporting weather conditions and a desire to learn more about how the weather can affect and impact our lives.You must also use the standard 4-inch rain gauge to measure your precipitation. Even if you already have some other type of rain gauge such as a digital or automatic gauge often included with home weather stations, you will need to use the standard rain gauge. For an explanation on why CoCoRaHS uses the 4 inch gauge, please go here.
How Do I Join
It's easy to sign-up to become an observer - click on "Join CoCoRaHS" and complete the on-line application form. Once you sign up, you will receive a login and password. After you have a rain gauge and begin making observations, you can log in and report them. Your precipitation observations will start showing up daily on our county maps.
