Atmospheric Resource Board

The Atmospheric Resource Board (ARB) is a quasi-judicial, quasi-legislative advisory and rule-making board under the supervision of the Water Commission. ARB is co-located with the Water Commission and functions as one of its divisions. The primary functions of the ARB are to:

  • Carry out administrative procedures required for the licensing of weather modification contractors and the permitting of cloud seeding operations and research activities;
  • Develop and maintain a system for the collection of data and records of all operational weather modification activities;
  • Conduct research into atmospheric precipitation processes to assess and improve the effectiveness of cloud seeding technology;
  • Promulgate rules and regulations governing cloud seeding activities to ensure environmental and public safety;
  • Monitor and evaluate cloud seeding activities and report back to sponsoring entities; and
  • Monitor, collect, and disseminate accurate precipitation and climate data.

Notice of Intention to Modify Natural Precipitation

The ARB has requested publishing of legal notices regarding the North Dakota Cloud Modification Project in the county newspapers of the NDCMP target area and adjacent counties. Please see our News & Info page for the notice text.

The newspapers include Adams County Record, Billings County Pioneer, Bowman County Pioneer, Burke County Tribune, Dunn County Herald, Golden Valley News, McKenzie County Farmer, McLean County Independent, Minot Daily News, Mountrail County Promoter, Mouse River Journal, Renville County Farmer, The Herald (Slope & Hettinger Counties), The Journal (Divide County), and the Williston Herald.

The last publishing date by these newspapers was Friday, March 10th. Therefore, the 20-day comment period will end on March 30th, 2017.

Real-time Radar from Bowman

ARB operates a weather radar at the Bowman airport all year. For 8 months of the year, the counties of Billings, Bowman, Dunn, Fallon (MT), Golden Valley, Harding (SD), Slope and Stark cost-share the operations of the radar. Radar images are updated every six minutes 24 hours per day, 7 days per week.

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.

Cloud Seeding Has Big Economic Impact in Western ND
