  • 1. Community Collaborative Rain, Hail & Snow Network Noah Newman
  • 2. What is CoCoRaHS??CoCoRaHS is a national made up of volunteers of all non-profit, ‘citizen backgrounds and ages . . . science’ network . . . who take daily measurements of precipitation right in their own backyards”
  • 3. All Types of Precipitation!Rain Hail Snow
  • 4. Why CoCoRaHS ??Precipitation is important and highly variable Data sources are few and rain gauges are far apart PRISM: used by permission
  • 5. CoCoRaHS was born in response to the 1997 Fort Collins, Colorado Flood
  • 6. The flood pointed out: 1. The extreme local variations in rainfall. 2. The important role individuals can play in measuring, mapping andA B reporting precipitation. Distance between A and B = 5 miles A = 14.5 inches B = 2.0 inches
  • 7. Once trained, ourvolunteers collect data using low-costmeasurement tools . . . Aluminum foil-wrapped 4-inch diameter Styrofoam hail pads high capacity rain gauges Training is important to assure accurate, high quality data
  • 8. and report their daily observations on ourinteractive Web site:
  • 9. Volunteer’s observations are immediately available in map and table form for the public to view.Fort Collins, Co Locally Nationally
  • 10. CoCoRaHS’s main focus is to provide:
  • 11. precipitation data . . . Albuquerque, NM Daily data in table form Daily precipitation maps: Rainfall, Hail and SnowfallThis data allows CoCoRaHS to supplement existing networks and provide many useful resultsto scientists, resource managers, decision makers and other end users on a timely basis.
  • 12. . . . as well as educational opportunities “Helping to provide the public with a better understanding of weather”
  • 13. CoCoRaHS data are used by many • Teachers and Students• National Weather Service – Aligned with State and• Other Meteorologists National Science Standards• Hydrologists – Taking measurements• Emergency Managers – Analyzing data• City Utilities – Organizing results -Water supply – Conducting research -Water conservation – Geography, Math, Writing, Art -Storm water• Insurance adjusters• USDA—Crop production• Engineers• Scientists studying storms• Mosquito control• Farm Service Agency• Ranchers and Farmers• Outdoor & Recreation
  • 14. What began as a community project Has turned into animportant nationwideprecipitation database
  • 15. “A Rain Gauge at Every School” will help achieve this goal …with the help from“Celebrate Colorado Water 2012”
  • 16. “A Rain Gauge at Every School” Lesson Plans and ActivitiesElementary School Middle School High School•Basic measurements •Basic measurements •Basic measurements•Computer data entry •Computer data entry •Computer data entry•Utilizing maps, charts •Utilizing maps, charts •Utilizing maps, chartsand graphs and graphs and graphs•Basic Activities •Basic Activities •Basic Activities •Intermediate •Intermediate measurements measurements •Data analysis •Data analysis •Lab experiments •Lab experiments •Advanced measurements •Advanced data analysis
  • 17. CoCoRaHS events:The ‘Make it Rain Game’
  • 18. How Can Five Easy Steps you get Sign-up on the involved? CoCoRaHS web page Obtain a 4” plastic rain gauge View the “training slide show” or attend a training session Set-up the gauge in a “good” location in your backyard Start observing precipitation and report
