Professional Experience of Professor Julius S. Chang
Professor Chang is a professor in the Department of Atmospheric Sciences and serves
as Dean of the College of Earth Sciences at National Central University, Chung-li,
Taiwan. In order to devote his full attention to these positions and to demonstrate his
commitment to NCU he took early retirement from the University at Albany, State
University of New York. In recognition of his past contribution and service, he was
awarded the title of Professor Emeritus by University at Albany, SUNY.
Professor Chang started his professional career as student researcher at two of the
foremost national research laboratories in the US, Los Alamos National Laboratory
(LASL) and Lawrence Livermore National Laboratory (LLNL). Starting as student
research assistant and then junior research staff and finally various senior and
management positions. Early works were in the area of computational physics and
modeling. Because of national security requirements, many works from this period of
his career are still not available in the open literature. During the early phase of this
period only selected works on computational techniques were published in the open
literature.
In early 1970s Prof. Chang participated in the Climatic Impact Assessment Program
(CIAP) of the US Department of Transportation. CIAP was mandated by US
Congress to study the potential environmental impact on stratospheric ozone from a
hypothetical fleet of civilian supersonic aircrafts operating in the stratosphere. By
1975 he had become one of the leading researcher in stratospheric chemistry and
transport modeling. He was the principal author in interpreting model findings on
protecting stratospheric ozone layer. He led the writing of a major volume of
findings for CIAP. In recognition of his work he was invited to serve as a member
of the Panel on Atmospheric Chemistry and Transport of the US National Academy of
Sciences from 1975 to 1982. And then in 1983 he also served on the Committee on
Causes and Effects of Changes in Stratospheric Ozone of the US National Academy
of Sciences. While serving on these committees he coauthored all the reports of
findings contributing to review of models and interpretation of modeling results. In
particular, he was a coauthor of the first definitive review and assessment report on
the impact of anthropological release of chlorofluoromethanes (CFMs) in the
atmosphere on stratospheric ozone.
During this period he also served as members of three US delegations to the
Coordinating Committee on Ozone Layer of the United Nations Environmental
Program. In that capacity he led the modeling interpretation and assessment groups
and the drafting of principal findings for UNEP for three separate reports. Over a
ten-year period he also served as consultant to the Atmospheric Sciences Division of
the World Meteorological Organization. He was elected to serve on the International
Commission of the Meteorology of the Upper Atmosphere of the International
Association of Meteorology and Atmospheric Physics (IAMAP). He was also
elected to serve on the International Ozone Commission (IOC) of IAMAP. He
served on the IOC for over 16 years and was elected to be its President in 1984. He
also served on the Scientific Advisory Committee of the US Federal Aviation
Administration and awarded the US Department of Transportation Certificate of
Commendation. He also was member of the organizational committee for three
NASA assessment reports on the State of the Stratosphere for which he received a
NASA Group Achievement Award.

While at LLNL Prof. Chang served as group leader of Geophysics Group and then
Computational Physics Group of the Theoretical Physics Division. Each of these
groups had over 10 researchers with Ph. D. degrees and a number of support scientists.
As head of Geophysics Group he oversaw works in atmospheric sciences,
hydrological modeling, underground coal gasification modeling, and solid earth fluid
mechanical modeling. As head of Computational Physics Group he was associated
with various high pressure and high temperature hydrodynamic modeling works.
He was also instrumental in developing a new research area in combustion modeling
which eventually became an internationally recognized research group. After
serving for 8 years as group leaders he then was promoted to the position of Deputy
Division Leader for Theoretical Physics. This division has over 70 Ph. D. researcher
and another 30-40 support computational scientists and junior physicists. He
participated in the fiscal and technical management of the division and in the annual
review of performances of all the staff. In addition, he continued with his work in
stratospheric modeling and led another group of researchers from the Atmospheric
Sciences Division conducting research of his own interest.
In 1982 a major reassessment of the state of science for numerical computational
modeling for acid deposition in North America was commissioned by USEPA to be
conducted by the National Center of Atmospheric Research (NCAR). NCAR invited
Prof. Chang to plan, organize and lead this study with the support of over 30 NCAR
scientists. The final report with Prof. Chang as the principal author concluded that
sufficient new scientific achievements justify the funding of a new model
development. He then was invited by NCAR to lead this interdisciplinary project.
He initiated the Acid Deposition Modeling Project (ADMP) at NCAR in 1983. It
became the critical central project of the National Acid Precipitation and Assessment
Program (NAPAP), a 10-year long national study. As Director of ADMP he served
directly under the Director of NCAR over seeing the works of over 20 Ph. D.
scientists and another 20 supporting professionals at NCAR and over 40
internationally recognized consultants covering all scientific processes involved in
atmospheric transport, transformation and deposition of acidic materials and
precursors. He was also responsible for technology transfer of the ADMP model to
USEPA. The resulting model, RADM, became the core model of NAPAP and
eventually the reference USEPA Agency acid deposition model and ozone pollution
model, Models-3/CMAQ. It is also the origin of the European standard model,
EURAD and the widely used air quality model in Taiwan, TAQM. Parts of RADM
are used in other models and the direct descendant of RADM, SAQM is one of the
standard models used in California, New York, Hong Kong and Australia.
The ADMP project was moved to University at Albany, State University of New York
in 1987. The final ADMP model RADM2 was completed there. With this move
Prof. Chang assumed his present position of Professor of Applied Sciences, a
university wide professorship. After completion of ADMP project Prof. Chang then
led the development of a new air quality model for the State of California. The new
model, SAQM, incorporated many advances in air quality modeling. Some of which
are adapted by the USEPA version of the model, Models-3/CMAQ. All these works
were done in early 1990s. Starting in 1989 Prof. Chang devoted much of his
attention to air quality modeling in Taiwan. He hosted the Ph. D. research of two
students from National Taiwan University and participated in many of the major
studies in Taiwan, such as the Acid Rain Research Project of Taiwan EPA, the
Southern Taiwan Air Quality Study, and the Central Taiwan Air quality Study. The
works of these students as applied to these studies led to the general acceptance of
5
TAQM by the environmental modeling community in Taiwan. At the height of the
critical environmental dispute on the potential damage of Lin-Kou Power Station on
surrounding area Prof. Chang developed the methodology and analysis that
conclusively resolved the dispute. Prof. Chang
professional association with a
number of groups in Taiwan is continuing. In 1988, He received a National Science
Council Lectureship at the Department of Atmospheric Sciences of the National
Taiwan University.
In 1994 he was awarded the distinguished Alexander von Humboldt Research Award
by the German government, the Alexander von Humboldt Foundation.
Since 1973 Prof. Chang has worked with a number of major research institutes in
Germany. That led to his effort in helping University of Cologne establish the
EUMAC modeling program, which then developed the EURAD model, a descendant
of RADM2. For the past 10 years EURAD has been a major model in Europe.
Other Institute had also adopted versions or parts of RADM2 modeling system in their
own works. In 1995 the Fraunhofer Institute for Environment Research (IFU) in
Germany started negotiation with Prof. Chang to seek his assistance in redirecting,
monitoring and reviewing the works of IFU numerical modeling division.
Eventually he agreed to serve as the Division Director for Numerical Modeling on a
part-time basis for two years. This is a division of over 15 researchers with 10 Ph. D.
level scientists. He led the identification of new goals and eventually the creation of
a new air quality model, MCCM. He ahs worked with IFU staff for several years in
testing and improving this model.
In 2004 Prof. Chang was awarded the Outstanding Scholar Award from the
Foundation established by Academician Yuan-Tseh Lee in Taiwan. Prof. Chang is
currently devoting his attention to developing a world class environmental modeling
system to bring Taiwan
research in this area to the attention of worldwide
environmental research community.
In summary, Prof. Chang has collaborated with scientists from over 20 countries, and
has been responsible for several nationally (US) important research programs. He
has developed new interdisciplinary projects and has experience in managing large
research groups. In addition, over the years, he has served on a number of high-level
review committees for major industrial corporations and national and international
bodies. A more detailed listing of his past positions and professional activities is in
the attached biography.
