Modeling the Distribution, Impacts, and Mitigation of Anthropogenic Heat in Los Angeles

Joseph Ko, Yun Li, Hannah Schlaerth, Stepp A. Mayes et autres

Abstract Anthropogenic heat emissions from human energy consumption contribute to the urban heat island (UHI) effect, yet their spatiotemporal distributions and impacts remain uncertain. In this study, we develop a 100 m resolution, hourly anthropogenic heat flux (AHF) data set for Los …

Does socioeconomic and environmental burden affect vulnerability to extreme air pollution and heat? A case-crossover study of mortality in California

Mehjar Azzouz, Zainab Falah Hasan, Md Mostafijur Rahman, W. James Gauderman et autres

Abstract Background Extreme heat and air pollution is associated with increased mortality. Recent evidence suggests the combined effects of both is greater than the effects of each individual exposure. Low neighborhood socioeconomic status (“socioeconomic burden”) has also been associated with increased exposure …

Albedo as a Competing Warming Effect of Urban Greening

Hannah Schlaerth, Sam James Silva, Yun Li, Dan Li

Abstract Urban greening is often proposed for urban heat island (UHI) mitigation because vegetation provides shade and increases evapotranspiration. However, vegetation has lower albedo and higher emissivity than the bare soil it often replaces, which increases incoming energy fluxes. Here, we use …

Characterizing Ozone Sensitivity to Urban Greening in Los Angeles Under Current Day and Future Anthropogenic Emissions Scenarios

Hannah Schlaerth, Sam James Silva, Yun Li

Abstract Cities are simultaneously implementing urban greening and reducing anthropogenic emissions to combat climate change, but these strategies can have complex and potentially counteracting effects on regional atmospheric chemistry. Urban greening can increase emissions of volatile organic compounds (BVOCs), while climate change …

The Effects of Heat and Air Pollution on Mental Health Related Mortality in California

Md Mostafijur Rahman, Melissa Lorenzo, Rob McConnell, Zainab Falah Hassan et autres

Background: Higher ambient temperature and air pollution may play a role in increasing the risk of mental health related mortality; however, findings vary depending on study location. We examined the relationship between temperature and air pollution with deaths due to suicide and …
