CoCoRaHS Volunteer Precipitation Data

Each time a rain, hail or snow storm passes, volunteers take measurements of precipitation from as many locations as possible. These precipitation reports are then recorded on our Web site The data are then displayed and organized for many of our end users to analyze and apply to daily situations ranging from water resource analysis and severe storm warnings to neighbors comparing how much rain fell in their backyards.
