Investigation of Particle Effective Density, Size Distribution and Dose Metric of Ambient Aerosol

Research Product Type

Dissertation / Thesis

The exposure to particulate matter (PM) has strong adverse health effects, such as aggravated asthma, decrease in lung function, and increase respiratory symptoms.

Large-Scale, Dynamic, Microscopic Simulation for Region-Wide Line Source Dispersion Modeling

Research Product Type

Dissertation / Thesis

Motivated by the challenges encountered in the previous modeling efforts, this work develops an advanced modeling framework for region-wide applications of line source dispersion models that integrates a high-performance emission rate lookup system (i.e., MOVES-Matrix), link screening, and innovative receptor site selection routines to further accelerate model implementation within distributed computing modeling framework.

Measurement and Estimation of Particulate Matter Concentration on Highways in Southern California; Characterization of Diesel Emissions using In-Door Smog Chamber

Principal Investigator Liem Pham
University of California, Riverside

In this study, both stationary and comprehensive mobile monitoring platforms were developed to measure PM concentration and traffic conditions on some major highways in Southern California. The main objective was to develop a set of alternative metrics that measure particle concentrations as well as particle size.
