INTRODUCTION <br /> <br />The long-range purpose of the Park Hange Atmospheric Water Resour- <br /> <br />ces Program is to determine the economic factors involved in augmenting at- <br /> <br />mospheric water resources in the Upper Colorado River Basin by artificial <br /> <br />nucleation operations. <br /> <br />The specific purpose of the program is to determine whether natural <br />precipitation can be increased in an area where the ice nuclei process of pre- <br />cipitation formation predominates and a strong orographic effect is present. <br />To attempt an increase, artificial ice nuclei (silver iodide crystals) are sup- <br />plied to the atmosphere where its temperature is less than OOC; the Park <br />Range ridge not only accentuates precipitation under natural conditions, but <br />will also encourage convective mixing of the artificial nuclei with the pas sing <br /> <br />alr mass. <br /> <br />This is an engineering research program, designed to provide a <br /> <br />cause and determine the magnitude of the resulting effect, The program is <br />I divided into two phase s; in Phase I the characteristic s of precipitation, nuclei <br />concentration and diffusion were determined under natural conditions; in the <br />I Phase II effort many of the storms passing through the area are being nucle- <br />ated artificially and re sult s compared with natural data to determine what <br />I effect has been caused, Appendix A. This report discusses the results of <br />the first year of Phase II operations. <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />The Park Range program is centered at Steamboat Springs in north- <br />central Colorado, Figures 1 and 2. It is a cooperative program adni.inister- <br />ed by the Bureau of Reclamation, operated by E. Bollay Associates, Inc., <br />with field as sistance from the U. S. Department of Agriculture- - Fore st <br />Se rvice and Soil Conse rvation Se rvice - - and further coope ration from Colo- <br />rado State University and the National Center for Atmospheric Research. <br />Phase I operations spanned the period 1 November 1964 through 30 June 1965 <br />and Phase II operations will cover the period 1 July 1965 through 30 June 1967. <br /> <br />- 1 - <br /> <br />-' <br />
