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.
  • Educate and provide information regarding the atmosphere and atmospheric processes.

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 five minutes 24 hours per day, 7 days per week.

Cloud Seeding Provides Significant Economic Impacts

A recent study from the NDSU Department of Agribusiness and Applied Economics (Bangsund and Hodur, 2019) describes the significant economic benefits cloud seeding provides to agricultural production in the western North Dakota counties of Bowman, McKenzie, Mountrail, part of Slope, Ward and Williams. Average annual benefits for the nine crops included in the study range from $12.20 to $21.16 per planted acre for the years 2008-2017. Considering cloud seeding operations cost about $0.40 per planted acre, the benefits far outweigh the costs.

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 us at (701) 328-2788, or via email.
