Kenneth L. Demerjian Atmospheric Chemistry Professor phone (518) 437- 8705 kld@asrc.cestm.albany.edu

Research / Publications / Abstracts/ Reports

Education:

B.A. (Chemistry), 1968, Northeastern University
M.S. (Physical Chemistry), 1970, The Ohio State University
Ph.D. (Physical Chemistry), 1973, The Ohio State University

Research Interests:

Chemistry of the troposphere, trace gas measurement and instrumentation development, chemical kinetic and mechanistic studies of atmospheric oxidation
processes, and chemical kinetic modeling.

The major theme of my research involves the study of chemical and physical processes affecting the fate of anthropogenic and biogenic emissions and their impact on
global cycles of trace atmospheric constituents. These processes are critical to our understanding of the "chemical climate" and air quality and environmental impacts
on local to global scales.

Specific ongoing research programs relate to the study of the chemical composition of the atmosphere and associated reaction processes contributing to the oxidizing
capacity of the atmosphere. These processes have direct implications on the formation of photochemical oxidants/ozone, aerosols and other chemical species
capable of modifying the radiative (light absorbing and scattering) properties of the atmosphere and acidify the environment.

Research studies include: 1) the development of spectroscopic optical absorption, chemiluminescent instrumentation and chromatographic techniques for the
measurement of trace atmospheric constituents; 2) intensive and long term field measurement campaigns at Whiteface Mountain of photochemical oxidants and
chemical species associated with the atmospheric photoxidation cycle; 3) diagnostic analysis and modeling studies of atmospheric processes using field measurement
data; and 4) the study of the chemical kinetic and mechanistic pathways of elementary atmospheric reactions and the development of reaction mechanisms of
polluted and clean atmospheres.
