The activities which are grouped together as “weather modification” cover a wide range and have important differences as well as similarities. Many governmental agencies in pursuing long standing interests in the relation of the atmosphere to their missions, have become involved in individual weather modification programs which are similar enough to prompt the assumption that their efforts are empire building, duplicative and competitive. Study of the details of what is going on provides little evidence that serious empire building or duplicative efforts are the rule.
Cooperation and coordination exist between Federal agencies but should be improved particularly in the areas of planning for the future and attracting the participation of the additional skilled people.
