Nolan Doesken  currently works part time for the Colorado Water Center and the Colorado Climate Center.  He  retired as State Climatologist for Colorado at Colorado State University in 2017. After obtaining degrees from the Univ. of Michigan and Univ. of Illinois in the 1970s, Nolan began his work as a climatologist at CSU in 1977 and was appointed State Climatologist in 2006.  He has long been fascinated with climate monitoring and long-term climate trends, but pays particularly close attention to precipitation including floods and drought.  After the Fort Collins flash flood of 1997, Nolan established a volunteer rain gauge network to track and map the local variations in northern Colorado precipitation.  This project -- the Community Collaborative Rain, Hail and Snow network (CoCoRaHS) -- has since grown internationally and involves thousands of volunteers across many parts of North America.  Nolan is a past president of the Ameican Association of State Climatologists and was a founding board member of the Citizen Science Association.
