<br />8. Operation Plan (continued) <br /> <br />and plibals. Also available will be radar data, half-hourly <br /> <br /> <br />satteliee maps from the National Weather Service, rawinsonde <br /> <br /> <br />data and other forecast aids to assist in selecting favorable <br /> <br /> <br />storm periods suitable for modification to achieve the intended <br /> <br /> <br />objectives. <br /> <br /> <br />3) Types of Aircraft: <br /> <br /> <br />There will be no aircraft used for seeding on this program. <br /> <br /> <br />All cloud nuclei generators will be. operated from the ground. <br /> <br /> <br />4) Description of the Seeding Devices, Materials and Seeding <br /> <br /> <br />Rates, et~. <br /> <br />Eight <br /> <br />( 8 ) <br /> <br />manually operated ground-based cloud nuclei <br /> <br />generators will be located within and around the project areas. <br /> <br /> <br />These manually operated generators will be the same type as used <br /> <br /> <br />on the Colorado River Basin Pilot Project and projects operated <br /> <br />by Western Weather Consultants, Inc. during the past six years. <br /> <br /> <br />In previous use, these generators have proven to be efficient nuclei <br /> <br /> <br />generators, safe and require very little maintenance. The solution <br /> <br />used will be a 4% silver iodide and a 1.25% sodium iodide solution <br /> <br />in acetone. The solution when burned in a propane flame at a rate <br /> <br /> <br />of 20 grams per hour per site will produce approximately 1016 <br /> <br /> <br />effective nuclei in cloud systems with a 500 mb temperature around <br /> <br /> <br />_200 C. This variable output generator will be operated at <br /> <br />races from 5 to 40 grams per hour depending on the seedability <br />of cloud conditions. <br /> <br />5) Description of How (he Project will be Implemented and <br /> <br /> <br />Carried Out: <br /> <br /> <br />The operational procedures to be used by the applicant to <br /> <br /> <br />achieve the stated objective are to produce silver iodide crystals <br /> <br /> <br />(artificial cloud nuclei) from the network of ground-based generators <br /> <br /> <br />for diffusion by favorable wind flows into selected storm or cloud <br /> <br /> <br />types favorable for reasonable precipitation increases over the <br /> <br /> <br />project area.
