William Wallace McMillan, Associate Professor of Physics at UMBC,
passed in March 2010.
He is greatly missed...
For the previous 16 years, Wallace was a valued member of the
UMBC
Physics Dept,
and the
College of Natural and
Mathematical Sciences.
Wallace was especially influential in the development of UMBC's PhD program in
Atmospheric Physics
for which he served as
Graduate Program Director from 2003.
He was also the Department liaison to the campus chapter of Phi Beta Kappa.
Wallace is remembered by his colleagues and friends for his collegial spirit,
sense of humor
(including his 'interesting' ties!),
and commitment to the success of students through his outstanding
service as a teacher and mentor.
A tribute to Wallace
is posted on the AIRS website and in
UMBC's student newspaper "The Retriever Weekly".
Education
Ph.D. Earth and Planetary Science, The Johns Hopkins University, 1992 M.A. Earth and Planetary Science, The Johns Hopkins University, 1990 B.S. Physics, Rhodes College, 1985, cum laude, Phi Beta Kappa
Previous Experience
Prior to joining the UMBC Physics Department, Dr. McMillan was a National Research Council Post-Doctoral Fellow with the Laboratory for Extraterrestrial Physics at the NASA Goddard Space Flight Center in Greenbelt, Maryland.
Professional Interests
Wallace's research in atmospheric physics involved measurements of the products of fire, particularly carbon monoxide, as tracers of atmospheric pollution.
[You can see a YouTube interview with Wallace regarding his research on
"UMBC In the Loop: Wallace McMillan & Forecasting Pollution from Space"].
Global, regional, and local measurements of pollution are necessary to monitor the health of the atmosphere, to assess human impacts on the environment, and to support forecasting of significant pollution events.
His research combined the analysis of satellite and ground-based
retrievals from infrared spectra of two key components of atmospheric
pollution: carbon monoxide (CO) and ozone.
As a member of the science team for NASA's Aqua satellite based
Atmospheric InfraRed Sounder (AIRS), he oversaw validation and optimization
of AIRS CO retrievals. His Atmospheric Remote-sensing Facility (ARF) is home
to the Baltimore Bomem Atmospheric Emitted Radiance Interferometer (BBAERI),
the first commercial prototype ground-based infrared sounder.
His research group studied
local and regional air quality, boundary layer mixing, climatic influences on biomass burning, and the exchange of gases between the troposphere and stratosphere. AIRS daily global views of CO enabled them
to see the motion of pollution similarly to our perspective of weather.
Analysis of regional aircraft data acquired through NASA field experiments
is critical to such integrated investigations in
collaboration with teams of national and international researchers
in atmospheric physics, chemistry, and dynamical modeling.
Products developed by ARF are retrievals of near surface CO2
from BBAERI and similar ground-based instruments.
