"CoCoRaHS," which stands for Community Collaborative Rain, Hail, and Snow Network, is a quick, easy, and inexpensive way to demonstrate real-life science in the classroom. In a nutshell, students measure rain that has collected in a rain gauge, or snow on the ground, and record and report their data. The students' data are then used by the National Weather Service (NWS) and a host of other governmental and public organizations every day.
Below is an example of a daily precipitation map for southern Indiana and central Kentucky that we produce here at the Louisville NWS office. These maps are highly dependent on CoCoRaHS reports, so the more CoCoRaHS observers we have the more accurate the map.
