A study of tropospheric photochemistry in the subtropical/tropical North and South Atlantic
(Georgia Institute of Technology, 1995-05)
Tropospheric O3 modeling study: Contributions of anthropogenic and biogenic sources to O3-CO and O3-CH2O correlations
(Georgia Institute of Technology, 2018-04-06)
Tropospheric O3 and CO are major pollutants in the troposphere. Strong correlation between O3 and CO was observed during the DISCOVER-AQ aircraft experiment in July 2011 over the Washington-Baltimore area. The observed ...
Isentropic ozone transport across the tropopause in the lower stratosphere and upper troposphere
(Georgia Institute of Technology, 2004-06-07)
Chemistry-climate interactions: Boundary layer ozone in the United States and free tropospheric methanesulfonic acid over the tropics
(Georgia Institute of Technology, 2015-11-16)
This work presents a multi-scale modeling analysis approach to explore two subtopics pertaining to the chemistry-climate interaction: (1) ground-level ozone pollution in the United States and (2) the marine sulfur chemistry ...
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 ...
Evaluation of Upper Atmospheric Ozone Data provided by a Differential-Absorption Lidar
(Georgia Institute of Technology, 2005-04-11)
Ground-level ozone is an environmental and public health issue. Daily ozone forecasts are made to allow people to take precautions to protect their health. For this study, a prototype laser that measures ozone concentrations ...
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 ...
Constraining global biogenic emissions and exploring source contributions to tropospheric ozone: modeling applications.
(Georgia Institute of Technology, 2006-06-26)
Biogenic isoprene plays an important role in tropospheric chemistry. We use HCHO column measurements by the Global Ozone Monitoring Experiment (GOME) to constrain isoprene emissions. Using the global Goddrad Earth Observing ...
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 ...
Planetary scale variations of stratospheric ozone as observed by SAGE
(Georgia Institute of Technology, 1981-12)
