Nolan Doesken

Nolan Doesken is a life-long weather enthusiast and has been working as a climatologist at Colorado State University since 1977. In his current position as State Climatologist for Colorado, Nolan is responsible for monitoring climatic conditions across the state and providing climate data, information and expertise to agencies, organizations, businesses and individuals who need it. Following a devastating flash flood in Fort Collins, Colorado in 1997, Nolan began a campaign to engage local residents in measuring and reporting rainfall from their back yards. With the help of many partnerships across the country, this project -- the Community Collaborative Rain, Hail and Snow Network (CoCoRaHS) -- has expanded to all 50 states and has over 15,000 active participants.
