Trends in urban air pollution over the last two decades: A global perspective
Abstract Ground-level ozone (O 3), fine particles (PM 2.5), and nitrogen dioxide (NO 2) are
the most harmful urban air pollutants regarding human health effects. Here, we aimed at …

Air quality and climate connections
Multiple linkages connect air quality and climate change. Many air pollutant sources also
emit carbon dioxide (CO2), the dominant anthropogenic greenhouse gas (GHG). The two …

Global estimates and long-term trends of fine particulate matter concentrations (1998–2018)
Exposure to outdoor fine particulate matter (PM2. 5) is a leading risk factor for mortality. We
develop global estimates of annual PM2. 5 concentrations and trends for 1998–2018 using …
