Iodine is an essential element in the human diet and a deficiency can lead to a number of
health outcomes collectively termed iodine deficiency disorders (IDD). The geochemistry of …

In the past 40 years, atmospheric chemists have come to realize that halogens exert a
powerful influence on the chemical composition of the troposphere and through that …

We present an updated mechanism for tropospheric halogen (Cl+ Br+ I) chemistry in the
GEOS-Chem global atmospheric chemical transport model and apply it to investigate …

We present a simulation of the global present-day composition of the troposphere which
includes the chemistry of halogens (Cl, Br, I). Building on previous work within the GEOS …

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 …

Halogen chemistry is well known for ozone destruction in the stratosphere, however reactive
halogens also play an important role in the chemistry of the troposphere. In the last two …

Iodine is a reactive trace element in atmospheric chemistry that destroys ozone and
nucleates particles. Iodine emissions have tripled since 1950 and are projected to keep …

Iodine is a critical trace element involved in many diverse and important processes in the
Earth system. The importance of iodine for human health has been known for over a century …

The amended and adjusted Montreal Protocol has continued to reduce emissions and
atmospheric abundances of most controlled ozone-depleting substances. By 2012, the total …

Despite the potential influence of iodine chemistry on the oxidizing capacity of the
troposphere, reactive iodine distributions and their impact on tropospheric ozone remain …
