The Direct Influence of Aerosols on UV Irradiance and the Development of a Synthetic Current UV Index
(Georgia Institute of Technology, 2006-07-11)
The extinction of solar radiation by atmospheric aerosols influences the Ultraviolet (UV) flux at the surface, which in turn has implications on both human and environmental health. In this study we present measurements ...
Influence of biomass burning aerosol on land-atmosphere interactions over Amazonia
(Georgia Institute of Technology, 2005-07-18)
The impacts of biomass burning smoke on local rainfall and the structure of the atmospheric boundary layer have been actively studied in recent years. However, whether the large-scale biomass burning in the later dry season ...
Reactions of Bromide Ions with Atmospheric Trace Gases and Aerosols
(Georgia Institute of Technology, 2006-01-13)
I investigated the utility of Br- as a chemical ionization mass spectrometry (CIMS) reagent ion for the detection and measurement of both atmospheric trace gases and aerosol species. The primary goals of this study are to ...
Representing droplet size distribution and cloud processes in aerosol-cloud-climate interaction studies
(Georgia Institute of Technology, 2009-05-04)
The indirect effect of aerosols expresses how changes in aerosols would influence clouds and cause impacts on Earth's climate and hydrological cycle. The current assessment of the interactions between aerosols and clouds ...
Real-time measurement of on-road fine particulate matter in Atlanta
(Georgia Institute of Technology, 2008-04-01)
Particulate matter is increasingly linked to health effects not only for what was previously thought to be just a respiratory problem, but also for the cardiovascular system. Literature not only supports that high particulate ...
Quantifying compositional impacts of ambient aerosol on cloud formation
(Georgia Institute of Technology, 2007-11-14)
It has been historically assumed that most of the uncertainty associated with the aerosol indirect effect on climate can be attributed to the unpredictability of updrafts. We assess the sensitivity of cloud droplet number ...
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 ...
Predictability of Current and Future Multi-River discharges: Ganges, Brahmaputra, Yangtze, Blue Nile, and Murray-Darling Rivers
(Georgia Institute of Technology, 2007-10-16)
The aim of this study is to determine the predictability of river discharge in several major rivers on time scale varying from weeks to a century.
We investigated predictability considering relationship between SST and ...
Developing and testing a coupled regional modeling system for establishing an integrated modeling and observational framework for dust aerosol
(Georgia Institute of Technology, 2009-01-09)
To this date, estimates of the climate response to mineral dust remain largely uncertain because of our limited capability to quantify dust distribution in the atmosphere. Focusing on the Central and East Asian dust source ...
