<br />., <br /> <br />~\.f:,'U <br /> <br />. <br /> <br />. <br /> <br />The southern portion of the Central Valley of California has <br />been a focal point of intense interest in cloud seeding. <br />Fresno State College Foundation has been retained to activate <br />a coordinated effort in the Southern Sierra region. The <br />desired result of this effort would be a joint experiment in <br />which cooperating seeding groups would conduct discreet <br />portions. This would minimize the conflict resulting from <br />one group's control area becoming another group's target <br />area. <br /> <br />New Mexico State University has recently begun a study aimed <br />at increasing the precipitation in the Upper Rio Grande River <br />Basin. Initially at least, they will be using ground-based <br />silver iodide generators. As their program develops, sub- <br />contractors will be called in to assist with some of the <br />field work. As with the other uni versi ty groups, New Mexico <br />State has a number of graduate students and interested faculty <br />members from other disciplines involved in the program. Thus, <br />young talent is developed, fresh ideas are introduced and <br />mature judgment is exercised. <br /> <br />J. Laboratory s'tudies <br /> <br />Laboratory research is aimed at discovering knowledge under <br />the controlled conditions not possible in a field study. The <br />research can include investigation of new seeding agents and <br />the behavior of seeding agents u.~der various conditions. <br />Also included in laboratory research is instrument and equip- <br />ment development. This frequently is done in conjunction with <br />field experiments, such as the design of new, remote-reporting <br />precipitation gages and snow pillows at Utah State University, <br />and the radar modifications at the University of Nevada and <br />South Dakota School of Mines. <br /> <br />Dr. T. G. Owe Berg is investigating the effect on the efficiency <br />of seeding agents of passage through the wann base of a cloud <br />where the temperature is warmer ti',an O. C and the cloud com- <br />posed of water droplets. The results of this study will help <br />detennine the proper method of dispensing seeding material. <br /> <br />Other laboratory studies are aimed at specifying the dimensions <br />of the plume of seeding material by determining the silver <br />content of snow or by detecting tracer elements in the air. <br />Several organizations are engaged in these studies. <br /> <br />4. Theoretical research <br /> <br />The purpose of theoretical research is to provide information <br />of a somewhat more basic nature which is, at the same time, <br /> <br />14 <br />
