Photoactive Roadways: Laboratory, Field and Modeling insight on the impact of photocatalytic paving materials on urban tropospheric chemistry
Photoactive roadways have been suggested as a mitigation method to improve air quality in urban areas. However, difficulties translating laboratory results to real world conditions has complicated a wider adoption of this ...
USING NASA EARTH OBSERVING SATELLITES WITH THE AIRPACT AIR QUALITY FORECAST SYSTEM
The Air Indicator Report for Public Awareness and Community Tracking (AIRPACT) air quality model simulates EPA criteria pollutants and their precursors, providing quantitative descriptions of regional air quality in the ...
Chemical Characterization of Biogenic Secondary Organic Aerosol Generated from the Oxidation of Plant and Leaf Litter Emissions
Atmospheric aerosol impact climate by scattering and absorbing radiation and contributing to cloud formation processes. One of the largest uncertainties in climate change predictions is due to limitations in our understanding ...
Measuring Diesel Exhaust Gas Phase Organics with a Thermal Desorption Proton Transfer Reaction Mass Spectrometer
Photochemical processing of organic compounds from vehicle emissions forms ozone and increases organic particulate matter concentrations through the formation of secondary organic aerosol (SOA), which is a poorly understood, ...
Impacts of industrial and biogenic emissions on air quality
Volatile organic compounds play important roles in atmospheric chemistry, air quality and wellness of human being. This dissertation investigated two air quality problems related to volatile organic compounds and compared ...
EXPERIMENTAL OBSERVATIONS OF NON-METHANE HYDROCARBONS AND NOX SOURCES IN URBAN AND RURAL LOCATIONS
Non-methane hydrocarbons (NMHCs) and NO + NO2 (NOx) are precursors for photochemical smog which includes particulate matter and ozone. NMHCs and NOx have both biogenic and anthropogenic sources. This work characterizes ...
