An airshed concept has been widely practiced in developed countries as a tool for air quality
mitigation, but its application in developing countries is still evolving. The air pollution …

Tropospheric ozone (O3) is a harmful gas compound to humans and vegetation, and it also
serves as a climate change forcer. O3 is formed in the reactions of nitrogen oxides and …

Formaldehyde (HCHO) plays an important role in atmospheric photochemistry and air
quality. In this study, to investigate the sources and characteristics of formaldehyde pollution …

Formaldehyde (HCHO) exposures during a full year were calculated for different
race/ethnicity groups living in Southeast Texas using a chemical transport model tagged to …

We studied the seasonal variations of volatile organic compounds (VOCs) in the Houston
metropolitan area in the summertime and wintertime of 2018. The analysis of hourly …

The complexity and heterogeneity of urban land surfaces result in inconsistencies in near-
surface winds, which in turn influence the diffusion and dispersion of air pollutants. In this …

The population of Texas has increased rapidly in the past decade. The San Antonio Field
Study (SAFS) was designed to investigate ozone (O 3) production and precursors in this …

This study mainly developed an estimate method for photochemical ozone (O 3) production
from urban plumes in hot season, through simulating O 3 evolution from precursors locally …

Ozone (O 3) pollution in city level is a complex issue that arises not only from local
photochemistry process but also involves mid-or long-range O 3 transport. In this study, we …

As criteria pollutants from anthropogenic emissions have declined in the US in the last 2
decades, biomass burning (BB) emissions are becoming more important for urban air …
