<br /> <br />~ ',. <br /> <br />Operation Plan (continued) <br /> <br />and p ibals. <br /> <br />Also available will be radar data, half-hourly <br /> <br />sattelite IIl8pS <br />data and other <br />storm periods <br /> <br />from the National Weather Service, rawinsonde <br />forecast aids to assist in selecting favorable <br />suitable for modification to achieve the intended <br /> <br />objectives. <br />3) Types of Aircraft: <br />There will be no aircraft used for seeding on this program. <br />All cloud nuclei. generators will be operated from the ground. <br />4) .Description of the Seeding Devices, Materials.and Seeding <br />" Rates." etc.: <br />'Eight (.8,) manually operated ground-based cloud nuclei <br />generators ~l be located within and around the project areas. <br />These, manually operated generators will be the same type as used <br />:. on the Colorado River Basin Pilot Project and projects. operated <br />. by Westem Weather Consultants during the past 22 years. <br />. . <br />., In.previous use, these generators have proven to be efficient nuclei <br />. . generators , safe and require very little maintenance. The solution <br />. used will be a 4% silver iodide and a 1.25% sodiUIII iodide solution <br />in acetone. The solution when bumed in a propane flsme at a rate <br />".. 16 <br />of 20 grams per hour per site will produce approximately 10 <br />effective nuclei in cloud systems with a 500 IIlbteiDperature around <br />" " , . <br />_200 C. Thia variable output generator will be. operated at <br />.., . . f'5" . ... ., <br />ra~es from 5 to~grSlllS per hour depending on the seedability <br />of cloud conditions. <br />~) Description of How the Project will be Implemented and <br />., .',. Carried Out: <br />.The operational procedures to.he used by the applicant to. <br />achieve the stated objective are to produce silver iodide crystals <br />(artificial cloud nuclei) from the network of ground-based generators <br />for diffusion by favorable wind flows into selected storm or cloud <br />types favorable. for reasonable precipitation increases over the <br />project area.
