RESEARCH INTERESTS
Simulation of
the physical, chemical and biological processes that
determine atmospheric composition. Development of (1) detailed
numerical models of photochemistry and atmospheric radiation, and (2)
global chemical transport models that describe ozone and other trace
gases. Studies include the predicted effects of volcanic sulfate
aerosols on stratospheric ozone loss, the role of clouds in scattering
sunlight and altering photochemistry, and the non-linearities in
chemical systems that lead to sudden changes such as the depletion of
ozone caused by CFC increases.
Numerical models
of atmospheric chemistry must simulate the
transport of trace species by winds, convective mixing, boundary layer
exchange with the surface, and exchange between the stratosphere and
troposphere. Such models are used to predict future changes in the
atmosphere and to analyze global data sets. Observed trace gas
distributions are used as measures of the atmospheric circulation or
alternatively as indicators of the location and strength of sources.
Such a quantitative understanding of these causal relationships is an
essential element of assessments of chemical and climatic change, and
it
is needed to convince governments and the public to make tough
environmental choices.
