China's past economic growth has substantially relied on fossil fuels, causing serious air
pollution issues. Decoupling economic growth and pollution has become the focus in …

The goal of the Tropospheric Ozone Assessment Report (TOAR) is to provide the research
community with an up-to-date scientific assessment of tropospheric ozone, from the surface …

Meteorological conditions play a crucial role in ambient air pollution by affecting both directly
and indirectly the emissions, transport, formation, and deposition of air pollutants. In this …

The discovery of causal relationships from purely observational data is a fundamental
problem in science. The most elementary form of such a causal discovery problem is to …

This chapter assesses the scientific literature describing expectations for near-term climate
(present through mid-century). Unless otherwise stated," near-term" change and the …

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 …

Reducing surface ozone to meet the European Union's target for human health has proven
challenging despite stringent controls on ozone precursor emissions over recent decades …

In support of the first Tropospheric Ozone Assessment Report (TOAR) a relational database
of global surface ozone observations has been developed and populated with hourly …

Atmospheric oxidation of isoprene, the most abundantly emitted non-methane hydrocarbon,
affects the abundances of ozone (O 3), the hydroxyl radical (OH), nitrogen oxide radicals …

US surface O 3 responds to varying global-to-regional precursor emissions, climate, and
extreme weather, with implications for designing effective air quality control policies. We …
