In any case, if a consistent result IS founri in a variety <br />of comparIsons, which have a sound physical basi s, then perhaps some <br />useful conclusions can be drawn. <br /> <br />A second factor relevant to the scope of research and evaluat i.)n <br />IS the limitations of available data. Because this was a first year <br />effort, the data base cannot be regarded as adequate (0 evaluate con- <br />clusively all aspects of the three basic physical hypotheses. On <br />the other hand, a number of important physical proce~c;f's and seedi ng <br />effects thereon can be examined and evaluated with data obtained during <br />the field program. <br /> <br />In the following section, this field program and thr- statistical <br />evaluation are summarized. <br /> <br />1.2 SUMMARY OF RESEARCH ACTIVITIES <br /> <br />1.2.1 Field research_ progra~~ According to the csn desi.?,:1 study, <br />an area in the '!y-alllu'- :1ountains_ east or Beaver, Utah, appears to be <br />representative of much of the l!tah weather modification treated area. <br />Also, accessibi 1 i ty was assessed to be favorable. Consequently, the <br />vicinity of Beaver and the mountains to the east was chosen as the <br />location for intensive data collection. The period of the field research <br />program was from February I to ~arch 31, 1981. <br /> <br />The strategy for collecting data was divided into two maIn parts. <br />In the first part. relatively short periods, four hours typically, were <br />selected for intensive data collection. During these periods all avail- <br />able measuring systems were operated according to predetermined methods. <br />In the second part, instruments capable of measuring and recording data <br />continuously were operated. <br /> <br />\{h i let h e de t a i Iso f d a t a c 0 I Ie c t ion act i vi tie s are g i v e n 1 n <br />Appendix A, only a summary wi 11 be provided here.
