<br />ACKNOWLEDGMENTS <br /> <br />Many individuals contributed to the SAA (Snow Accumulation Algorithm) development, <br />especially in the areas of data collection and analyses discussed in this report. Lt. Col. <br />Tim Crum (retired) had the vision of a need for a snow algorithm for the NEXRAD <br />(NEXt generation weather RADar) network. He initiated the process leading to the SAA <br />development. He and Jerry Klazura were very helpful during about the first half of the <br />SAA work, both coordinating with various agencies and providing general guidance <br />concerning OSF needs and opportunities. Their high degree of interest in this project is <br />greatly appreciated. Their positions were later filled by Lt. Col. Andy White and Mark <br />Fresch who have continued the high le:vel of cooperation this project has enjoyed with <br />the OSF. Special thanks are due to Tim O'Bannon of the OSF for his considerable <br />technical advice and support throughout the project. <br /> <br />Several National Weather Service (NWS) personnel provided assistance in SAA <br />development and testing at the Albany, New York, Cleveland, Ohio, Denver and Grand <br />Junction, Colorado, and Minneapolis, Minnesota, Forecast Offices. The main contacts in <br />these respective offices were John Quinlan, Bob LaPlante, Dave Imy, Ellen Heffernan, <br />and Rich Naistat. All were quite cooperative and generous with their time. Others <br />helped significantly with data collection over the Sierra Nevada (Mark Heggli, California <br />Dept. Water Resources and Captain Dave ValleI'd, USAF), the Cascades (Brad Colman, <br />NWS SOO, and Mark Moore, USFS NW Avalanche Center), and in Alaska (Neal <br />Marchbanks and Jeff Perry, both NWS). Personnel at the NSSL (National Severe Storms <br />Laboratory) were very helpful in conv1erting the SAA to real-time use on their Warning <br />Decision Support System; Kevin Thomas and J.T. Johnson deserve special recognition. <br /> <br />Many people, too numerous to mention, were involved in data collection as volunteer <br />snow board observers or paid gage operators. Almost all of these people did a first rate <br />job. Jack McPartland of Reclamation deserves special mention for his careful gage site <br />selection and gage calibration and installation at several locations. NCDC, with the able <br />assistance of John Kobar provided numerous Levelll tapes to this project at no cost. <br />Drs. James Heimbach of the University of North Carolina at Asheville and Paul Smith of <br />the South Dakota School of Mines and Technology provided significant technical advice <br />to this project. Linda Rogers and Anne Reynolds performed meticulous gage chart data <br />reduction. In addition, Linda was heavily involved in data processing and analyses over <br />much of the project period while Anne provided considerable programming support. <br />The main project programmer was Ra Aman who developed a wealth of complex <br />software in FORTRAN, C, and Script. His abilities are most impressive. <br /> <br />This work was primarily supported by the WSR-88D (Weather Surveillance Radar-1988 <br />Doppler) OSF (Operational Support Facility) and the Next Generation Weather Radar <br />Program. Significant additional support was provided by the Bureau of Reclamation's <br />Research and Technology Transfer Program, directed by Dr. Stanley Ponce, and by the <br />NOAA (National Oceanic and Atmospheric Administration) Office of Global Programs <br />GEWEX (Global Energy and Water Cycle Experiment) GCIP (Continental-Scale <br />International Project) directed by Dr. Rick Lawford. <br /> <br />iii <br />
