Research Interests: Atmospheric chemistry, climate change.
Stratospheric
ozone depletion and global warming are two of the most important
global environmental issues of the 20th and 21st centuries. The
broader issues of atmospheric chemistry and climate change are
the focus of my research. The atmospheric chemical system has
important effects on humans through pollutants such as smog or
particulates, through acid rain, and through stratospheric ozone
change. Climate can be altered by greenhouse gases, solar variability,
volcanic eruptions, aerosols, and ozone, and of course affects
people and ecosystems. Given the complexity of both the Earth's
climate and chemical systems, computer models are required to
unravel the physical ways in which these various factors work.
In much of my research, I simulate the coupled climate and chemical
systems to better understand interactions between the two. Examples
of such interactions are plentiful. Stratospheric ozone depletion
allows more UV radiation into the troposphere, changing the rate
at which greenhouse gases are oxidized. A warmer climate leads
to increased methane emissions from wetlands, leading to further
warming and increasing ozone pollution. Enhanced solar irradiance
increases the production of stratospheric ozone, changing the
climate. These types of interactions can be important on many
time scales, so I have simulated times from 55 million years ago
to the 17th century to the 20th century and in to the future.
