AEROSOL OBSERVATIONS FROM SPACE, AIRCRAFT AND SURFACE ANALYZED WITH A GLOBAL MODEL
(2011-08-09)We interpret satellite, aircraft, and ground-based measurements using the GEOS-Chem Chemical Transport Model (CTM) to better understand the global transport and distribution of fine aerosol (PM2.5). Using satellite ... -
Chemical Analysis of Fine Particulate Matter Measured Worldwide through Global Air Sampling Network
(2021-04-29)Globally consistent measurements of airborne metal concentrations in fine particulate matter (PM2.5) are important for understanding potential health impacts, prioritizing air pollution mitigation strategies, and enabling ... -
Global Trends in Satellite-Derived Fine Particulate Matter & Developments to Reactive Nitrogen in a Global Chemical Transport Model
(2022-12-16)At present, air pollution is the leading global environmental risk factor for premature mortality. Highly respirable fine particulate matter (PM2.5) dominates this global burden of disease, while ozone makes smaller but ... -
Influence of model spatial resolution on simulated aerosol surface concentration
(2016-11-22)Fine particulate matter known as PM2.5 exists in Earth’s atmosphere at varying levels globally. High ambient concentrations of PM2.5 are associated with adverse health impacts, reduced visibility, and have a relatively ... -
INSIGHT INTO GLOBAL GROUND-LEVEL AIR QUALITY USING SATELLITES, MODELING AND IN SITU MEASUREMENTS
(2015)Ground-level air quality depends on the ambient concentration of atmospheric aerosols and trace gases. We applied information on aerosols and trace gases gathered from satellite remote sensing, in situ observations, and ... -
INTERPRETING SATELLITE REMOTE SENSING, AIRCRAFT AND GROUND-BASED OBSERVATIONS OF AEROSOL USING A CHEMICAL TRANSPORT MODEL
(2020-01-16)Fine particulate matter (PM2.5) is the leading environmental risk factor for the global burden of disease. Black carbon (BC) and metal components are primarily responsible for the adverse health effects associated with ... -
Quantifying the Spatiotemporal PM2.5, Black Carbon, and Ultrafine Particle Concentrations Aboard Public Buses in Brazil: A Comparison of Three Cities
(2018-03-26)The transportation environment contributes disproportionately to air pollution exposure, despite the short amount of time spent in this microenvironment. Elevated concentrations of air pollution within bus passenger cabins ... -
Studying Source Contributions to Ambient Fine Particulate Matter and Estimating Its Historical Concentrations
(2020-10-13)Long-term exposure to ambient fine particulate matter (PM2.5) is a major health concern. This thesis presents three projects that take advantage of chemical transport modeling, ground-based monitoring and satellite remote ...
