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 ...
A comparison of NMHC oxidation mechanisms using specified gas mixtures and trace-P field data
(Georgia Institute of Technology, 2005-11-15)
This work has focused on showing the differences among four different NMHC oxidation mechanisms: GT Lurmann, CBIV, RACM, and SAPRC mechanisms. This study was carried out to characterize these mechanisms using both specified ...
Spring to Summer Transitions of Ozone and Its Precursors over North America and Photochemistry over Antarctica
(Georgia Institute of Technology, 2007-06-28)
The horizontal and vertical distributions of ozone and its precursors over North America during spring and summer are frequently determined by several factors: cloud convection, lightning NOx production, mixing depth, and ...
On the processes and mechanisms affecting carbonyl sulfide and carbon monoxide photoproduction in natural waters
(Georgia Institute of Technology, 1997-05)
A comparison of photochemistry at rural sites in the Southeastern United States and Southeastern China
(Georgia Institute of Technology, 1994-08)
Experimental determination of the photolysis rate coefficients of nitrogen dioxide and ozone
(Georgia Institute of Technology, 1993-12)
Investigation of Mineral Dust Aerosols - Chemistry Intractions in the Marine Environments
(Georgia Institute of Technology, 2007-08-24)
Mineral dust aerosols play an important role in atmospheric chemistry through photolysis and heterogeneous uptake. Both mechanisms strongly depend on the size and composition of mineral dust. Because of the complex nature ...
