CoCoRaHS — an acronym for the Community Collaborative Rain, Hail, and Snow Network — began in New Jersey on Groundhog Day (February 2nd), 2008. The CoCoRaHS network of volunteer weather observers has rapidly expanded to include over 14,000 active observers in all 50 states. Through the use of low-cost measurement tools and by emphasizing training, CoCoRaHS volunteers take accurate daily observations of precipitation and snow cover. These measurements are then entered onto a web form, sent to a central archive, and displayed through the CoCoRaHS website for timely use by end users such as meteorologists, hydrologists, farmers, water resource managers, and the general public.

All that's required to be a CoCoRaHS participant is the desire to watch and report weather conditions, access to an internet-connected computer, and the appropriate measurement tools (a 4" diameter plastic rain gauge and a ruler).

We look forward to welcoming you to the CoCoRaHS network in NJ!
