A comprehensive study of Titan's magnetic pile-up region during the Cassini era
(Georgia Institute of Technology, 2020-04-28)While Saturn's largest moon Titan is devoid of an intrinsic magnetic field, draping of the giant planet's magnetospheric field around Titan's ionosphere generates a pile-up region at the moon's ramside. In this study, we ... -
A concise survey of the occurrence and varying formation environments of feldspathic rocks in the southern highlands, Mars
(Georgia Institute of Technology, 2016-12-09)Presented here, is a synthesis of previous studies that have resulted in the discovery of feldspathic material on the Martian surface through the utilization of orbital (e.g., OMEGA on Mars Express and CRISM on MRO) and ... -
A coral ensemble record of the El Niño southern oscillation over the mid-to-late holocene
(Georgia Institute of Technology, 2017-07-28)The El Niño-Southern Oscillation (ENSO) represents the largest source of year-to-year global climate extremes. However, its sensitivity to external climate forcing, whether natural or anthropogenic, is difficult to assess ... -
A multiscale analysis of heat transfer in porous media
(Georgia Institute of Technology, 2017-11-02)The modeling of thermal convection in porous media is a challenging task due to the inherent structural and thermophysical heterogeneities that permeate over several scales. In the present thesis, I address several issues ... -
A satellite and ash transport model aided approach to assess the radiative impacts of volcanic aerosol in the Arctic
(Georgia Institute of Technology, 2014-01-10)The Arctic radiation climate is influenced substantially by anthropogenic and natural aerosols. There have been numerous studies devoted to understanding the radiative impacts of anthropogenic aerosols (e.g. those responsible ... -
Advanced methods for real-time identification and determination of seismic events
(Georgia Institute of Technology, 2022-12-20)Natural disasters pose an indistinguishable threat to populations all around the world, affecting ~200 hundred million every year, with earthquakes being the most deadly. Global seismic monitoring allows for robust real-time ... -
Advancing Assessments on Aerosol Radiative Effect by Measurement-based Direct Effect Estimation and through Developing an Explicit Climatological Convective Boundary Layer Model
(Georgia Institute of Technology, 2006-11-09)The first part of the thesis assesses the aerosol direct radiative effect (ADRE) with a focus on ground-based AERONET and satellite MODIS measurements. The AERONET aerosol climatology is used, in conjunction with surface ... -
Aerosol characterization in the Southeastern U. S. using satellite data for applications to air quality and climate
(Georgia Institute of Technology, 2012-01-19)Tropospheric aerosol information from NASA satellites in space has reached the milestone of ten years of continuous measurements. These higher resolution satellite aerosol records allow for a broader regional perspective ... -
An AFM study of calcite dissolution in water and selected amino acids
(Georgia Institute of Technology, 1997-12) -
An airborne field study of dimethylsulfoxide at tropical latitudes and its relationship to the Marine sulfur budget
(Georgia Institute of Technology, 2001-08) -
The Amazon hydrometeorology: climatology, variability and links to changes in weather patterns
(Georgia Institute of Technology, 2009-07-27)Using ERA40 and independent observations, I assess how well Amazon surface water budget is estimated. ERA40 basin wide annual precipitation (P) agrees with observations showing an underestimation of 10%, whereas runoff (R) ... -
The Ambient Organic Aerosol Soluble in Water: Measurements, Chemical Characterization, and an Investigation of Sources
(Georgia Institute of Technology, 2006-05-03)This thesis characterizes the ambient fine organic carbon aerosol and investigates its sources through the development and deployment of new measurement techniques. The focus is on organic compounds that are soluble in ... -
Ambient Submicron Particles In North America: Their Sources, Fate, and Impact
(Georgia Institute of Technology, 2007-10-04)This thesis improves the understanding of the fate and transport of aerosols in North America. Aerosols play an important role climate modification, visibility, human health, and regulatory compliance. Through multiple ... -
Anaerobic reduction of manganese oxides and its effect on the carbon and nitrogen cycles
(Georgia Institute of Technology, 2012-04-04)The biogenic reduction of Mn(IV) oxides is one of the most favorable anaerobic electron transfer processes in aquatic systems and likely plays an important role in the redox cycle of both carbon and nitrogen in anaerobic ... -
Analog and numerical experiments investigating force chain influences on the bed physics of dense granular flows
(Georgia Institute of Technology, 2014-03-31)Granular materials are composed of solid, discrete particles and exhibit mechanical properties that range from fluid to solid behavior. Some of the complexity exhibited by granular systems arises due to the long-range order ... -
Analyses of Atmospheric Pollutants in Atlanta and Hong Kong Using Observation-Based Methods
(Georgia Institute of Technology, 2004-08-04)There are two parts in this study. The first part is to test the validity of the assumption of thermodynamic equilibrium between fine particulate (PM2.5) nitrate and ammonium and gas-phase nitric acid (HNO3(g)) and ammonia ... -
