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 …

Online coupled mesoscale meteorology atmospheric chemistry models have undergone a
rapid evolution in recent years. Although mainly developed by the air quality modelling …

Severe surface ozone pollution over major Chinese cities has become an emerging air
quality concern, raising a new challenge for emission control measures in China. In this …

Assessment of spatial and temporal variation in the impacts of ozone on human health,
vegetation, and climate requires appropriate metrics. A key component of the Tropospheric …

In China, ozone pollution shows an increasing trend and becomes the primary air pollutant
in warm seasons. Leveraging the air quality monitoring network, a random forest model is …

We use 2009–2011 space-borne methane observations from the Greenhouse Gases
Observing SATellite (GOSAT) to estimate global and North American methane emissions …

Atmospheric deposition of Hg (II) represents a major input of mercury to surface
environments. The phase of Hg (II)(gas or particle) has important implications for deposition …

Atmospheric volatile organic compounds (VOCs) are not only harmful to human health, but
also lead to ozone (O 3) formation. From July 3 to August 1 of 2018, online measurements of …

From the earliest observations of ozone in the lower atmosphere in the 19th century, both
measurement methods and the portion of the globe observed have evolved and changed …

We implement a new isoprene oxidation mechanism in a global 3‐D chemical transport
model (GEOS‐Chem). Model results are evaluated with observations for ozone, isoprene …
