ARB Recruiting Observers to Report Precipitation

We are recruiting volunteers to observe and report precipitation across North Dakota. Volunteers have the option of participating in the ARB Cooperative Observer Network (ARBCON), either year-round, or only during the months of April-September. If you or someone you know have any interest in volunteering, contact Dan Brothers at (701) 328-2788, or via email at dabrothers@nd.gov.


Snow Reporting Comes To ARBCON

The Atmospheric Resource Board Cooperative Observer Network (ARBCON) began reporting snow data for the first time in it's 34 year history on October 1, 2010. More than 400 of ARBCON's 750 volunteer observers signed up to report year-round. The additional snow data will help fill gaps in existing snow data networks, assisting forecasters in predicting spring runoff and flooding risk. Learn more about ARBCON snow reporting here .
