Also available will be radar data, 'halt-hourly <br />sattelite maps from the National Weather Service, r.vfD8onde <br />data and other forecast aids to assist in selecting tavorable <br />storm periods Buitable for modification to achieve the intended <br />objectives. <br />J) Types of Aircraft: <br />There will be no aircr.ft used for seeding on this program. <br />All cloud nuclei generators will be operated from the ground. <br />4) Descripcion of che SeedinB Devices, Materials .nd SeedinR <br /> <br />. <br /> <br />Rates~ etc.: <br /> <br />Twelve (12) manually oper.ted 8'l'ound-baeed cloud nuclei <br />gener.tors will be located within and around the project .reaa. <br />Theae manually oper.ted generators will be the .... ~e .a uaed <br />on the Colorado River Basin Piloc Project and projecta oper.ced <br />by Weecern Weather Consultant., Inc. during the pa.t .ix' years. <br />In previous use, these gener.tors have proven to be etticient nucl.i <br />gener.tors, s.fe and require very little ..~tenance. The solucion ,~ <br />us.d will be . 4% silver iodide and a 1.25% aodi_ iodide solucion <br />in ac.Cone. Th. solution when burned in a propane fIa.e at a rac. <br />of 20 grams per hour per siC. will produc. .pproxiaatelyl016 <br />effective nuclei in cloud syscems with.. 500 mb c_peracure .round <br />_200 C. This variable output ,enerator will be oper.ted at <br />rate. from 5 to IS grams per hour dependina on che .eedabllity <br />of cloud conditiona. <br />5) Description of How the Project will be Im~lemented and <br />Carried Out: <br />The. operational procedures to be used by the applicant to <br />achieve the stated objective are to produce silver iodide'cryst.la <br />(artificial cloud nuclei) from the network of ground-b.aed g.nerators <br />for diffusion by favorable wind flows into select.d storm or cloud <br />types favorable for reasonable precipitation incr..... over the <br />project area.
