Tutorial 1

Introduction to Aerosols 1:  Particle Aerodynamics, Diffusion, and Size Measurement 

Richard C. Flagan, Department of Chemical Engineering,  California Institute of Technology, Pasadena, CA

Abstract: This tutorial is the first of two that introduce the broad field of aerosol science.  We begin with the behavior of individual particles to understand how they behave in the environment, and the physical principles on which most aerosol measurements are based.  The drag forces that act on a particle determine its settling velocity and whether it is able to follow the flow of a gas.  Several different models describe the drag forces: Stokes law applies for spherical particles moving at modest velocities, though a slip correction must be introduced to account for noncontinuum effects for particles small compared to the mean-free-path of the gas molecules.  Other corrections are required if the velocity becomes large enough the fluid inertia affects the motion.  Knowledge of these scaling principles makes it possible to relate particle behavior in seemingly disparate systems, and make it possible to determine particle size.  The drag forces also determine Brownian motion, and, hence, affect their deposition and losses in the respiratory tract, in sampling systems, and in filters, causing aerosol filtration to be more effective than filtration of particles from liquid media.  We will briefly look at how this aerodynamic behavior is employed in determining particle size in a wide range of instruments, including the migration of charged particles in mobility analyzers.

Tutorial 2

Field and Mobile Atmospheric Aerosol Measurement: Principle and Practice

Charles Brock, Chemical Sciences Division, NOAA Earth System Research Laboratory, Boulder, CO

Abstract: Studying the atmospheric aerosol often means setting up temporary measurement systems at field sites or sampling from mobile platforms such as vans, aircraft, or ships. Obtaining a representative sample in such conditions can be challenging, to say the least. This tutorial will first discuss how the physics, chemistry and thermodynamics of aerosol particles must be considered when developing a system for quantitative aerosol sampling and measurement. We will then explore practical solutions to common sampling problems, including inlet design for sampling from aircraft, simple techniques to minimize diffusional and inertial particle losses, and approaches to control thermodynamic changes to the aerosol. Next we will discuss how to choose instruments and develop flow and pressure control strategies for sampling in a rapidly changing environment, such as on an aircraft. We'll finish by discussing data processing issues, such as sample interval and time synchronization, that are commonly found with multi-instrument datasets, are often only an afterthought, and can compromise analysis of the collected dataset. Attendees should leave not only with a checklist of concerns, but with a toolbox of approaches and the confidence to adapt and apply them to their specific circumstances.

Tutorial 4

Biomarkers of Air Pollution Exposure

Roby Greenwald, Department of Environmental Health, Rollins School of Public Health, Emory University,  Atlanta, GA

Abstract: Exposure to ambient air pollution is associated with a wide variety of chronic and acute health outcomes. Although the precise mechanisms remain unclear, investigation of the biological processes linking exposure to outcomes is currently a very active area of research. An ever-expanding array of biomarkers is being developed to facilitate the examination of intermediate steps in the health response to air pollution. This tutorial will present an overview of biomarkers available for health-related research and will include discussion of biomarkers relevant to all physiological systems. Biomarkers appropriate for human subjects’ research will be emphasized, and ethical issues related to the invasiveness of sample collection will be discussed. The advantages and disadvantages of various biological media (such as plasma, whole blood, dried blood spots, exhaled breath, urine and saliva) and analytical methodologies will be examined.

Tutorial 5

Introduction to Aerosols 2:  The Particle Size Distribution and Its Dynamics

Richard C. Flagan, Department of Chemical Engineering, California Institute of Technology,  Pasadena, CA

Abstract: This tutorial continues the basic introduction to aerosol science.  In this session we focus on developing the tools to describe the dynamics of aerosol populations.  An aerosol is an ensemble of particles in a gas, and the particles are distributed over a range of sizes.  Therefore, they must be represented by a particle size distribution.  We will discuss the representation of aerosol populations as size distributions, their graphical representation, and models such as the log normal-distribution.  Condensation and evaporation of volatile species onto particles determines their growth in the atmosphere, and efficient counting of particles too small to detect optically in condensation particle counters.  Both continuum and noncontinuum effects must again be considered, as must the surface tension which governs particle activation, initial activation, and the possibility of nucleating new particles from the vapor phase.  These processes also alter the shape of the size distribution.  Particle-particle collisions lead to coagulation, which further alters the size distribution.  We will examine how these diverse processes are combined to describe the population dynamics for aerosol systems.

Tutorial 6

Hands-on Aerosol Instrumentation Design and Measurement

Moderated by Tyler Beck, Particle Instruments, Vadnais Heights, MN

Abstract:  This tutorial will enable participants to get an “under the hood” look at a broad spectrum of currently available aerosol instruments.  Whether you are an experimentalist, modeler, or both, this is an opportunity to learn how fundamental aerosol scientific principles are used in actual aerosol measurement technologies.  Key capabilities, as well as limitations, of each technique will be described in order to instill a better appreciation for what different instruments can, and cannot, do.  Various aerosol instrumentation suppliers will present the design, concepts, and engineering choices that led to the successful development of different aerosol instrumentation.  The tutorial is not a marketing and sales opportunity for participating vendors; this is an educational session with an emphasis entirely on technology and the key physical concepts employed by the instrumentation.  A primary goal is that by the end of the tutorial participants no longer consider instrumentation a “black box” but rather have some understanding of the principles and design considerations that went into the development of the various instruments.  A secondary goal is that participants will use the information presented on measurement uncertainties and limitations to better avoid over-interpreting measurement results.

Tutorial 7

Stochastic Simulations of Aerosol Dynamics

Amit Chakrabarti, Kansas State University, Manhattan, KS and Chris Hogan, University of Minnesota, Minneapolis, MN

Abstract: This tutorial will introduce attendees to the application of Monte Carlo, Molecular Dynamics, and Brownian Dynamics based approaches to modeling the motion of particles in the gas phase (aerosols).  In the first half of the tutorial, the basic principles behind these simulation techniques will be introduced, including the computational generation of uniformly distributed and Gaussian distributed random variables, random number sampling from probability distributions, and the parameterization of distribution functions.  Monte Carlo approaches will then be introduced generally, with a focus on non-equilibrium particulate systems undergoing aggregation. The second half of the tutorial will then discuss the application of stochastic differential equations to systems which are not in equilibrium, including diffusion dynamics at the single particle level, Brownian dynamics, and Molecular Dynamics. In particular, concepts of a Link-List will be introduced as well as the Velocity-Verlet Algorithm and solution techniques for the Langevin Equation.  Specific applications of these techniques to particle aggregation, free molecular drag calculations, and particle/ion motion in the presence of electrostatic interactions will be discussed.

Tutorial 9

Chemical Characterization of Atmospheric Particles by Off-line Methods of Analysis

Alexander Laskin, Environmental Molecular Sciences Laboratory, Pacific Northwest National Laboratory, Richland, WA

Abstract: Fundamental understanding of the complex chemistry of atmospheric aerosols, their physico-chemical properties and environmental impacts is a challenging task because no single method of analytical chemistry is capable of providing the full range of analytical chemistry information.  Electron microscopy and micro-spectroscopy approaches can visualize individual particles and their internal structures; however, they largely exclude molecular-level information, and are limited to elemental and chemical bonding characterization.  Contemporary methods of high-resolution mass spectrometry can provide detailed information on the molecular content of organic aerosol, but these methods use bulk particle samples and provide no knowledge of the individual particle composition. 

Therefore, application of complementary analytical methods of chemical analysis is necessary for comprehensive characterization of aerosol composition and properties ranging from bulk molecular composition of aerosol organic constituents to microscopy level details of individual particles. Combined assessment of the results provided by these complementary analytical approaches offers unique insights to understand the composition and physico-chemical properties of atmospheric aerosols determining their effects on air quality and climate.  This tutorial will give an overview of new and emerging experimental techniques for off-line analysis of atmospheric particles, and applications of these techniques in fundamental studies of aerosol chemistry.

Dr. A. Laskin is a chief scientist at Pacific Northwest National Laboratory, Richland, WA.  His research is focused on physical and analytical chemistry of environmental particles and include laboratory and field studies focused on the understanding of chemical composition and physical properties of atmospheric aerosols. His group and collaborators apply an array of complementary analytical techniques for comprehensive chemical characterization of particles ranging from particle microscopy to molecular-level characterization of complex organic constituents of aerosols.  Research findings of his group are relevant to a number of issues related to atmospheric chemistry of sea salt, mineral dust, soot, SOA and biomass burning particles.  His present and past research interests include: environmental impact of aerosols; physical chemistry of gas-particle interactions; novel methods of aerosol collection and measurement; single-particle analysis of aerosols; high-resolution mass spectrometry of atmospheric organics; combustion related aerosols; combustion chemistry and chemical kinetics.


Tutorial 10

Fires in the Earth System: From Emissions to Impacts

Christine Wiedinmyer, Atmospheric Chemistry Division, NCAR Earth Systems Laboratory, National Center for Atmospheric Research, Boulder, CO

Abstract: Open burning, whether wildland fires, prescribed burning, burning as part of agricultural practices, and even the burning of waste and biofuels, emits significant amounts of trace gases and particulate matter to the atmosphere. These emissions can play an important role in local and regional air quality, global atmospheric chemistry, and climatic processes. This tutorial will summarize some of the recent advances and challenges in the estimation of emissions from open burning. The mechanisms by which emissions from biomass burning impact to air quality, climate, and further, how these interactions may change in the future will be reviewed. Finally, ongoing research to understand associated with the burning of waste materials and biofuels will be introduced.

Advanced Vehicles, Emerging Technologies, and Their Impact on Particulate Emissions

Kent C. Johnson, Thomas Durbin, George Karavalakis, David Cocker, and Wayne Miller
Emissions and Fuels Research, University of California Riverside, Center for Environmental Research and Technology, Riverside, CA

Abstract: Primary and secondary aerosol emissions impact our environmental and health from its global warming potential to its chemical and physical impacts. Aerosol characterization, formation, and understanding are needed as we innovate new technologies to meet our global objectives. Recently a wave of new technologies has resulted due to a desire in reducing greenhouse gases (GHG) emissions. Light duty vehicles have implemented direct injection gasoline techniques to achieve like-diesel performance, but at the expense of an increase in PM mass and a lower particle size distribution. Natural gas vehicles are taking on a larger role in our heavy duty mobile fleet due to low fuel costs. These NG vehicles may be lower in PM mass, but their ultra-fine PM emissions have been found to be significant due to differences in oil contributing to the exhaust emissions. New ocean going vessels have demonstrated lower PM emissions from ultra-low sulfur fuels. Interestingly marine PM mass has been reduced, but not the overall black carbon emissions under some conditions. In this tutorial I will take you on a journey of advanced vehicles and emerging technologies and their impaction on aerosol formation and its interaction with the environment.

Dr. Johnson joined CE-CERT's research faculty in 2009 after serving on the Center's staff as principal development engineer and manager of the Mobile Emissions Laboratory (MEL) and other laboratories. He has worked in the field of emissions and their interaction with the environment for over 20 years. He received his PhD in chemical and environmental engineering from UC Riverside where his doctoral research focused on the impact of emissions on ambient air quality. The main objective of Dr. Johnson’s research is to improve our understanding of the impact of emissions on our environment. The research interests include: 1) quantification of in-use emission measurements; 2) advancement of measurement techniques; 3) characterization of particulate matter (PM), and 4) study of fuel impacts on emissions for diesel engines. Recently his research has expanded to include the characterization of advanced vehicles (natural gas, hybrid, and full electric heavy duty vehicles) and their in-use performance and impact on the environment which includes climate change.
