A few of Our Most Popular Questions Weather Modification can be both planned, as is the case in cloud seeding, or inadvertent, for example, when pollution affects visibility. Planned (deliberate) weather modification is also commonly know as cloud seeding, cloud modification, or atmospheric water management. Weather Modification Certified Managers, Operators, Pilots and Field Technicians Why Does It Matter? What are the Benefits? WMA certifications are based on criteria that are intended to ensure the administrative, meteorological, aviation, and technical understanding, as well as commitment to ethical principles, of those conducting and managing cloud seeding operations. These principles are outlined in the ASCE guidelines for weather modification. The utilization of certified members for seeding programs is of benefit to the public, both in helping to recognize and take advantage of seeding opportunities during storm events, as well as recognizing and responding to potentially hazardous situations where seeding may not be desirable. Certification is based on criteria that include education, experience in the field of weather modification, and in-depth knowledge of the corresponding meteorological/aviation/field technician processes.
