Particulate mercury in the atmosphere: Its significance, transport, transformation and sources
(Kluwer Academic Publishers; Springer Science+Business Media, 1995-02)
The importance of particulate mercury (Hg(p)) in the transport, chemistry and deposition of this toxic metal has long been underestimated and largely ignored. While it was once believed to constitute a small percentage of ...
An intensive multi-site pilot study investigating atmospheric mercury in Broward County, Florida
(Kluwer Academic Publishers; Springer Science+Business Media, 1995-02)
An intensive multi-site pilot study of atmospheric Hg was conducted in Broward County, Florida in August and September of 1993. Broward County, which contains the city of Fort Lauderdale, is located in southeastern Florida. ...
Source Attribution, Physicochemical Properties and Spatial Distribution of Wet Deposited Mercury to the Ohio River Valley
(2009)
Mercury (Hg) is a bioaccumulative neurotoxin that is emitted from anthropogenic sources through fossil fuel combustion. The spatial scale of atmospheric transport prior to deposition is dependent on the chemical and physical ...
Aerosol Indirect Effects in a Coupled Global Aerosol and Atmospheric Circulation Model.
(2009)
The aerosol indirect effect remains one of the largest uncertainties in the projection of the future climate change. In this dissertation we improve both aerosol and cloud treatments in a coupled aerosol and atmospheric ...
Advanced Instrumentation and Flux Mapping Techniques for the Study of the Space Environment.
(2008)
The study of particle populations such as the solar wind, pickup ions, and energetic
particles, provides clues to the physical processes that govern the space environment.
Some of these particle populations are not well ...
Studies of Magnetospheric Convection: Balanced and Unbalanced.
(2008)
During active times, the magnetosphere can enter into different modes of convection. Three of the most common modes are: steady magnetospheric convection (SMC), isolated substorms, and sawtooth injections. This thesis ...
On Mars Thermosphere, Ionosphere and Exosphere: 3D Computational Study of Suprathermal Particles.
(2009)
Unlike Earth and Venus, Mars with a weak gravity allows an extended corona of hot light species and the escape of its lighter and hotter constituents in its exosphere. Being the most important reaction, the dissociative ...
Modeling and Technology Development for Sensitive Near-Solar Particle Measurements.
(2008)
The focus of this dissertation is the advancement of near-solar in-situ particle measurement techniques. Populations of dust, neutral atoms, and pickup H+ ions from 1.4 to 305 solar radii (Rs) are numerically modeled and ...
Summary of Dataset for Updated Solar and Space Physics 2024 Job Ad Study
(2024-03-11)
The previous 2013 Solar and Space Physics Decadal Survey (NRC, 2013) compiled the number of job ads posted in the AGU SPA and the AAS SPD Newsletters for postdoc, research scientist and faculty positions (Moldwin et al., ...
