The ARB has been involved in weather modification research since its creation by the legislature in 1975. Weather modification research in North Dakota, however, goes back to research pilot programs that were conducted over parts of western North Dakota during the 1960s. Many advancements in cloud seeding technology, especially in the area of hail suppression have come as a direct result of research and operations in North Dakota.
Polarimetric Cloud Analysis and Seeding Test (POLCAST)
Hygroscopic flare burns below cloud
POLCAST is a hygroscopic seeding research project designed to help determine if this type of seeding could help increase rainfall and reduce damaging hail from summer thunderstorms. The initial operational phase of the program, a cooperative venture between NDARB, UND, Weather Modification Inc., and Ice Crystal Engineering, was conducted from July 10-August 5, 2006.
The second phase, POLCAST2, involved the original parties with the addition of the National Center for Atmospheric Research (NCAR) and was conducted from June 9 - July 11, 2008. Phase two incorporated predetermined, randomized selection of candidate clouds for seeding to strengthen statistical results. Final reports on phase two are expected by December 31, 2009.
