  • NDCMP Operation Areas - A map showing where cloud seeding occurs in North Dakota during the summer.
  • Aircraft, Radar and Seeding Equipment - Fly along with a top seeder and a base seeder and see some photos of aircraft, radar and seeding equipment used during the NDCMP.
  • Pilot Internship Program (996 kb) - The ND Atmospheric Resource Board and the University of North Dakota's John D. Odegard School of Aerospace Sciences have been cooperating since the mid-1980's in an effort to provide appropriate experience for students and young professionals in the weather modification aviation industry. At the completion of the 2014 program, this internship has provided training and experience to over 343 pilots. Nine students are accepted every year. Click the link to find out more!
  • NDCMP History - A historical summary of cloud seeding in North Dakota.
  • Radar Images - Current radar images from the Bowman and Stanley Radars. Bowman radar operates year-round, while Stanley operates from approximately May 15-September 15 each year. Radar volume scans are completed every six minutes and updated images are posted immediately thereafter. Flight tracks for cloud seeding aircraft are displayed when they are flying, but do not indicate whether they are actively seeding or only doing reconnaissance.
