CoCoRaHS


CoCoRaHS is the Community Collaborative Rain, Hail and Snow Network. CoCoRaHS is a unique, non-profit, community-based network of volunteers of all ages and backgrounds working together to measure and map precipitation (rain,hail and snow). By using low-cost measurement tools, stressing training and education, and utilizing an interactive Web-site, our aim is to provide the highest quality data for natural resource, education and research applications Wyoming. Wyoming is a very active state, with almost 300 observers who regularly participate in the program. To learn more or to join CoCoRaHS, visit the CoCoRaHS homepage.

CoCoRaHS in Wyoming is supported by partnerships with WRDS-SCO, the National Weather Service and the USDA Farm Service Agency.

Wyoming currently has about 470 active observers and over 325 have reported at least once during 2014 Summer months see a higher number of observers and reports per day than in the winter, but a typical month (average of the last 12 months) has about 190 reports per day from about 260 observers.

Wyoming has a very high per capita participation in the CoCoRaHS network and we who use the data are very appreciative of all the efforts of the observers.

If you are interested in participating, we'd be grateful to have you in the network. There are a few things that you will need:

  • Internet Access (since you are reading this webpage, it's likely that you have this!)
  • An interest in measuring precipitation
  • Training (Training Slide Shows)
  • A 4-inch rain guage like the one in the photo to the right

At the moment, and until further notice, I will provide a complimentary gauge to any new sign ups in Wyoming. Simply enter the word WY-SCO-02 in the box labeled "How did you find out about CoCoRaHS?" on the sign up page (Sign Up)
