<br />- <br /> <br />CHAPTER 1 <br />JNTRODUCTION <br /> <br />Five winter seasons of randomized weather modification <br />operations have been complE~ted on the Colorado River Basin Pilot <br />Proj ect using the basic theory and cloud modification models estab- <br />lished during the Climax Program (Climax, Colorado). This fifth <br />year of operations completes the test of the Pilot Project as originally <br />designed. The goal' of the Pilot Proj ect is to determine if cloud <br />seeding can assist in meeting the mounting demand for additional water <br />in many parts of our nation and provide a sound evaluation of precipi- <br />tation increases. <br /> <br />e <br /> <br />EG&G's objective within this Pilot Project is to establish <br />and operate a ground-based instrumentation network to provide meteor- <br />ological data in and near the project area, and to establish and operate <br />a ground-based silver iodide seeding system to increase snowfall in the <br />proj ect area. EG&G will also establish, refine, and provide sound <br />scientific weather modificatilon procedures for producing increases in <br />snowfall over large areas of the San Juan and adjacent mountains for <br />future, fully operational wea~ther modification programs. <br /> <br />The Comprehensive Atmospheric Data Report provides a <br />compilation of the meteorological data that can be used to support the <br />seeding activities during the 1974-75 operating season. The compiled <br />data in this volume is primarily intended for use by the Pilot Proj ect <br />Evaluation Contractor in analyzing and evaluating precipitation events <br />resulting from seeded and uIlseeded (natural) cloud systems (the seeding <br />data are contained in a companion report, Comprehensive Seeding Report, <br />AL 1173). The entire report is largely a data compilation; however, it <br />does present operational summaries and analysis material. <br /> <br />This volume (Comprehensive Atmospheric Data Report, AL <br />1172) consists of two main sections: <br /> <br />A. The first main seetion is composed of four chapters, which <br />provide a general discussion of the pI' oj ect, changes from the initial <br /> <br />e <br /> <br />1-1 <br />
