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 ... -
INFERRING ATMOSPHERIC AEROSOL PROPERTIES FROM SATELLITE OBSERVATIONS AND A GLOBAL CHEMICAL TRANSPORT MODEL
(2020-09-11)Atmospheric aerosols have significant impacts on climate and human health. However, the exact magnitude of the climate and health effects of aerosols remains highly uncertain, due to the large variability in aerosol physical ... -
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 ... -
Interpretation of Arctic Black Carbon Measurements with a Chemical Transport Model
(2015-01-15)Black carbon is a pollutant of concern in the Arctic; however models struggle to accurately simulate its seasonal cycle observed from in-situ measurements. This work aims to examine the contribution of different types of ... -
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 ...
