Fellow ofthe American Meteorological Society and the Cooperative Institute for
Research in the Atmosphere (CIRA) at Colorado State University. He has published over
140 papers in peer-reviewed journals, eight chapters in books, authored one book, and co-
authored two books. He has supervised over 35 Ph D. and 38 M.S. students.

His weather modification experience includes his doctoral dissertation research,
as a team member on the NOAA Florida Area Cumulus Experiment, modeling studies of
dynamic seeding and seeding of winter orographic clouds, and as the author of several
review papers on weather modification, and co-author of several books reviewing
planned and inadvertent weather modification concepts and status.

Mr. Byron L. Marler Mr. Marler has over 30 years of experience in applied
meteorology. He is currently employed by Pacific Gas and Electric Company (PG&E)
with headquarters in San Francisco and one of the largest service areas in the US. He
supervises eight professionals, providing oversight and quality assurance on technical
assignments ranging from weather modification operations, climate analyses, operational
weather forecasting, air quality impact assessments, in-field measurements programs, and
research projects. He is PG&E's expert on weather modification, having worked on the
Lake Almanor and Mokelumme cloud seeding projects in the Sierra Nevada since 1975.
He has led PG&E research projects in weather modification technology, including
effectiveness evaluations, trace chemistry studies, ice-nuclei generator technology, cloud
seeding model development, and snowfall measurement. He has performed design
studies for cloud seeding programs for other utility companies and has had experience in
the preparation of environmental impact assessment documents for operational cloud
seeding programs.

Dr. Harold D. Orville (Chair) Dr. Orville is a Distinguished Professor Emeritus in the
Department of Atmospheric Sciences at the South Dakota School of Mines and
Technology. He served two terms as Interim Vice President of the University (1987,
1993) and as Head of the Department for 20 years. Dr. Orville joined the staff of the
Institute of Atmospheric Sciences early in 1965. Since that time he has worked on
cumulus dynamics and precipitation physics. In 1982, he served his sabbatical year as
Leader of the Scientific Planning Group for the Precipitation Enhancement Project, a
World Meteorological Organization sponsored activity. He served as a member of the
Cloud Physics Committee, the Severe Local Storms Committee, and the Weather
Modification Committee (Chairman, twice) of the American Meteorological Society, was
elected a Councilor of the Society, and served on its Executive Committee. He was
Chairman of the WMO Executive Council Panel of Experts/Committee on Atmospheric
Sciences Working Group on the Physics and Chemistry of Clouds and Weather
Modification Research from 1991 to 1999. He chaired the BASC committee in late 2000
that reviewed advancements in weather modification over the past 20 years.

Dr. Joseph A. Warburton Dr. Warburton is Executive Director Emeritus of
Atmospheric Sciences at the Desert Research Institute, University of Nevada in Reno.
His Ph.D is in Physics, the dissertation was "The Role of Particulates in Atmospheric
Processes". He came to the US from Australia to develop the trace chemical techniques
for measuring the very low concentrations of cloud-seeding chemicals in precipitation.
