<br />could possibly obtain additional funds from Federal agencies, <br />such as the National Science Foundation, for carrying out specific <br />experiments related to winter weather modification technology. <br />These experiments would be carried out in harmony with the basic <br />program and would provide their own additional instrumentation, <br />as necessary. This type of scientific research should be encour- <br />aged and sought by the program's management group, as it will <br />contribute to the scientific and technical knowledge regarding <br />weather modification and aid the program in achieving its primary <br />objective of defining the effects of cloud seeding operations for <br />various winter cloud systems. <br />The purpose behind the proposed program plan is to verify the <br />ability of this seeding technology to augment the winter snowpack <br />in mountainous regions within the State without impacts that fore- <br />close the application of the technology. The key measurements will <br />be the amounts of water resulting from the winter precipitation <br />over the entire seeded and downwind region that could be affected <br />by the seeding. In addition, atmospheric soundings and possibly <br />radar observations will be required in order to accurately identify <br />seedable conditions. These soundings will also provide indispens- <br />able data for evaluating the program. The data monitoring portion <br />of this program, which includes monitoring of surface precipitation <br />and associated atmospheric conditions, needs to be supported as <br />part of this plan by the State and Federal agencies. Some of the <br />necessary instrumentation could possibly be provided by Federal <br />agencies on a loan basis. The remaining equipment necessary for <br />the precipitation and atmospheric monitoring could be leased or <br />purchased, depending upon the amount of funding available. <br />Additional specialized monitoring equipment might include <br />various types of radars and instrumented cloud physics aircraft. <br />Recording wind systems should be installed near a number of re- <br />presentative generator sites to aid in identifying seedable <br />situations. Diffusion studies should be conducted under the pre- <br />dominant types of weather conditions. Ice crystals could be <br />replicated on a few occasions during both seeded and non-seeded <br />storms so that the ice crystal characteristics of the snow falling <br /> <br />-36- <br /> <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />
