Do you enjoy observing the weather or recording weather conditions in your own backyard? Do you like to keep track of how much rain or snow fell at your location? If so, consider joining the CoCoRaHS network.

Every morning, CoCoRaHS observers record important measurements of how much rain, hail, or snow fell at their location during the previous 24 hours and send that information out via the CoCoRaHS web page.

Volunteers of all ages and backgrounds (citizen scientists) are measuring precipitation in their own backyards as part of CoCoRaHS - the Community Collaborative Rain, Hail and Snow Network. This network has grown to more than 15,000 volunteer observers in every state of the country.  More volunteers are needed! 

It's fun, easy and only takes a few minutes a day to participate!

Joining the CoCoRaHS program is free, however all observers are required to purchase and install an official CoCoRaHS rain gauge to ensure accuracy and consistency from all observations. Cost of the rain gauge is around approximately $30 and can be purchased from a link on the CoCoRaHS web site.

We need observers throughout central Illinois and are especially interested in finding observers in the following counties:
