You can determine just how much rain, hail, or snow fell in your backyard and report it to build a weather data network second to none by joining the Community Collaborative Rain, Hail, and Snow Network (CoCoRaHS). This program helps meteorologists, researchers, the media, and others see and study the variability of precipitation across Iowa. The accumulated precipitation data will be available to anyone using the web.
