This Review aims to summarize the current understanding of bulk tropospheric aqueous-
phase chemistry. Because a complete review of all developments in this area would be …

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 …

We describe the baseline coupled model configuration and simulation characteristics of
GFDL's Earth System Model Version 4.1 (ESM4. 1), which builds on component and coupled …

Abstract Fine particulate matter (PM2. 5) decreased by 30–40% across China during 2013–
2017 in response to the governmental Clean Air Action. However, surface ozone pollution …

Surface ozone is a severe air pollution problem in the North China Plain, which is home to
300 million people. Ozone concentrations are highest in summer, driven by fast …

Observations of surface ozone available from∼ 1,000 sites across China for the past 5 years
(2013–2017) show severe summertime pollution and regionally variable trends. We resolve …

Atmospheric ozone (O3) is a pollutant produced through chemical chain reactions where
volatile organic compounds (VOCs), carbon monoxide and methane are oxidized in the …

Aerosol− cloud interactions account for the largest uncertainty in current estimates of
changes in radiative forcing according to the most recent IPCC report. 1 The term “aerosol …

Our understanding of the processes that control the burden and budget of tropospheric
ozone has changed dramatically over the last 60 years. Models are the key tools used to …

Peroxyacetyl nitrate (PAN) formed in the atmospheric oxidation of non-methane volatile
organic compounds (NMVOCs) is the principal tropospheric reservoir for nitrogen oxide …
