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 comprehensive simulation of tropospheric chlorine within the GEOS-Chem
global 3-D model of oxidant–aerosol–halogen atmospheric chemistry. The simulation …

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 …

Nitryl chloride (ClNO 2) is a dominant source of chlorine radical in polluted environment, and
can significantly affect the atmospheric oxidative chemistry. However, the abundance of …

We present a global simulation of tropospheric iodine chemistry within the GEOS-Chem
chemical transport model. This includes organic and inorganic iodine sources, standard gas …

Monochloramine, dichloramine and trichloramine (NH2Cl, NHCl2, NCl3) are measured in
the ambient atmosphere, in downtown Toronto in summer (median 39, 15 and 2.8 ppt) and …

Mercury (Hg) is a contaminant of global concern, and an accurate understanding of its
atmospheric fate is needed to assess its risks to humans and ecosystem health. Atmospheric …

Chlorine (Cl) radicals from photolabile chlorine species are highly reactive and can affect
the fate of air pollutants in the atmosphere. Although several campaigns have been …

Dinitrogen pentoxide (N 2 O 5) and nitryl chloride (ClNO 2) are key species in nocturnal
tropospheric chemistry and have significant effects on particulate nitrate formation and the …

Molecular chlorine (Cl2) and nitryl chloride (ClNO2) concentrations were measured using
chemical ionization mass spectrometry at a rural site over the North China Plain during June …
