A three-dimensional global dynamical and chemical model of methane
(Georgia Institute of Technology, 1990-05)
Formaldehyde instrument development and boundary layer sulfuric acid: implications for photochemistry
(Georgia Institute of Technology, 2008-03-31)
This work presents the development of a laser-induced fluorescence technique to measure atmospheric formaldehyde. In conjunction with the technique, the design of a compact, narrow linewidth, etalon-tuned titanium:sapphire ...
A study of tropospheric photochemistry in the subtropical/tropical North and South Atlantic
(Georgia Institute of Technology, 1995-05)
Three-Dimensional Model Analysis of Tropospheric Photochemical Processes in the Arctic and Northern Mid_Latitudes
(Georgia Institute of Technology, 2005-08-24)
Halogen-driven ozone and nonmethane hydrocarbon losses in springtime Arctic boundary layer are investigated using a regional chemical transport model (CTM). Surface observation of O3 at Alert and Barrow and aircraft ...
Investigation of Photochemistry at High Latitudes: Comparison of model predictions to measurements of short lived species
(Georgia Institute of Technology, 2006-10-10)
Recent field campaigns have measured enhanced levels of NOx (NO+NO2) and HOx precursors (i.e., H2O2, CH2O, and HONO) that can not be accounted for by gas phase chemistry alone. Snowpack emission is now considered a source ...
Investigations of the Emissions and Fate of Anthropogenic Air Pollutants from East Asia Using Regional On-line and Off-line Chemistry-Climate Modeling System
(Georgia Institute of Technology, 2004-04-08)
The work presented in this thesis document reflects the results of a study carried out to better quantify the magnitude and fate of the anthropogenic air pollutants emitted from East Asia. Simulations of anthropogenic ...
Urban Impacts On Atmospheric Chemistry: Surface Ozone in Large Versus Small Urban Centers and Urban Pollution in Asian Dust Storms
(Georgia Institute of Technology, 2006-08-11)
In Part 1, we separated surface ozone time series collected from EPA monitoring sites in and around Georgia from 1980-2002 using a Kolmogorov -Zurbenko Filter to assess the influences associated with characteristic timescales ...
Photochemical Formation and Cost-Efficient Abatement of Ozone: High-Order Sensitivity Analysis
(Georgia Institute of Technology, 2004-09-20)
The abatement of ground-level ozone has been a priority of air pollution policy because of its harmful effects on human health, ecosystems, and climate. The responsiveness of ozone to emissions of its principal precursors, ...
Photochemistry in the tropical Pacific troposphere : studies with a global 3D chemistry-meteorology model
(Georgia Institute of Technology, 1996-12)
An investigation of large-scale tropical biomass burning and the impact of its emissions on atmospheric composition
(Georgia Institute of Technology, 1994-08)
