Observational evidence shows the ubiquitous presence of ocean-emitted short-lived
halogens in the global atmosphere,–. Natural emissions of these chemical compounds have …

CH4 is the most abundant reactive greenhouse gas and a complete understanding of its
atmospheric fate is needed to formulate mitigation policies. Current chemistry-climate …

As the third most important greenhouse gas (GHG) after CO 2 and methane, tropospheric
ozone (O 3) is also an air pollutant causing damage to human health and ecosystems. This …

Tropospheric ozone (O 3) is an important surface pollutant in urban areas, and it has
complex formation mechanisms that depend on the atmospheric chemistry and on …

China is the largest contributor to the global total anthropogenic mercury (Hg) emissions.
However, the trend in anthropogenic Hg emissions in recent years in China has not been …

While the dominant role of halogens in Arctic ozone loss during spring has been widely
studied in the last decades, the impact of sea-ice halogens on surface ozone abundance …

Iodine at the ocean's surface impacts climate and health by removing ozone (O 3) from the
troposphere both directly via ozone deposition to seawater and indirectly via the formation of …

We implement the GEOS-Chem chemistry module as a chemical mechanism in version 2 of
the Community Earth System Model (CESM). Our implementation allows the state-of-the …

In the past decade, China has motivated proactive emission control measures that have
successfully reduced emissions of many air pollutants. For atmospheric mercury, which is a …

Isoprene, arguably the most studied biogenically emitted gas, is thought to have a large
impact on tropospheric composition. Other naturally emitted species have been considered …
