<br />2 CONClUS IONS <br /> <br />The recently initiated snow research effort at ARC has provided a <br />preliminary look at the potential for snow augmentation in the southern <br />Canadian Rocky Mountains. Current research efforts are focusing on the analysis <br />of the data collected during the previous field seasons. A continuing <br />climatological study will attempt to delineatle the snow climate and assist in <br />the design of any possible seeding projects. Limited aircraft measurements, the <br />first of their kind in Canada, indicate the presence of some liquid water in <br />winter clouds over the mountains and a relative low amount of naturally <br />occuri ng ice crystals. Further ana lys is of thi s data will assi st in assessing <br />the magnitude of this potential. <br /> <br />3 FUTURE PLANS <br /> <br />A proposal for a two-stage SNOWATER project has been submitted to the <br />Al berta Government. Duri ng the fi rst stage, "I ast i ng three snow seasons, snow <br />augmentation technology would be transfered and adapted to the Alberta <br />situation. Measurement systems proposed include a liquid water radiometer, <br />C-band and K-band Doppl er radars, a surface-based 2D-C probe, two radi osonde <br />stations, three data collection platforms~ and three remote controlled <br />ground-based generators. A cloud physics aircraft and a research seeder <br />aircraft are also proposed for in-situ obsE!rvations and controlled seeding <br />experiments. During the second stage of SNOWATER, lasting several snow seasons, <br />a full scal e seedi ng experiment woul d be conducted to demonstrate the use of <br />snow augmentation technology. <br /> <br />Several factors unique to the southern Alberta Rockies would be <br />considered during the experimental design activities in the first stage. These <br />include multiple barriers upwind of east slope target ridges, sharp lee-side <br />terrain "drop 01'1'", colder winters associated with a more northerly latitude, <br />presence of a provincial boundary near the proposed SNOWATER experimental area <br />and availability of storage facilities for snowpack runoff. Should a decision <br />be made to support the SNOWATER proposal, ill comprehensive project planning <br />document will be developed and steps taken to acquire the hardware and <br />experimental sites required. <br /> <br />ACKNOWLEDGEMENTS <br /> <br />The authors would like to acknowledge and thank our colleagues at the <br />Alberta Research Council. Most of the description of the aircraft system was <br />provided by D. Rogers. R.M. Myrick assisted in the processing of much of the <br />aircraft data. INTERA Technologies operated the research aircraft used during <br />the winter field programs.
