12 cloud seeding experiments and for studies of lightning characteristics. The type of lightning discharge most likely to ignite forest fires has been identified. High output airborne and ground based silver iodide generators have been developed. Utilizing data from the experimental area and a network of lightning survey stations, physical and mathematical models of mountain thunderstorms are being developed. ‘I* Project Skyfire is providing the basis for achiev- ing a significant reduction in lightning damage in the forest areas of the western United States, which is of appreciable benefit to the country. The objectives of Skyfire clearly fall within the mission responsibilities of the U.S. Forest Service, which should continue to be responsible for the project. The present program has been underway for over ten years. From the data presented to the Panel, it appears that this effort has been underfunded in rela- tion to its potential value to the agency’s mission, and to the Nation. I recommend, and regard as minimal, the following effort proposed by Agriculture: 1. 2. Expanded lightning investigations at the Missoula Experimental site and at the Northern Forest Fire Laboratory. Performance of larger scale seeding experi- ments in two well instrumented experimental areas in the National Forests of the Northern Rockies. A capability should be developed, by strengthening research resources already available, to operate these experimental areas either separately or simultaneously. * United States Department of Agriculture, Summary of Weather Modification Research Program presented on June 28, 1966.
