TL;DR: In this article, the authors present a simulation of the global present-day composition of the troposphere which includes the chemistry of halogens (Cl, Br, I) including emissions of inorganic iodine from the oceans, anthropogenic and biogenic sources of halogenated gases, gas phase chemistry, and a parameterised approach to heterogeneous halogen chemistry.

TL;DR: The US Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) program's Carbonaceous Aerosol and Radiative Effects Study (CARES) carried out in June 2010 in Central Valley, California, was a comprehensive effort designed to improve the understanding of the possible interactions between urban and natural emissions in the production and transformation of atmospheric aerosol and the resulting impact on climate change.

TL;DR: In this paper, a global simulation of tropospheric iodine chemistry within the GEOS-Chem chemical transport model is presented, which includes organic and inorganic iodine sources, standard gas-phase iodine chemistry, and simplified higher iodine oxide (I2OX, X, X) chemistry, photolysis, deposition, and parametrized heterogeneous reactions.

TL;DR: In this paper, the results of two research flights (RF12, RF17) over the tropical Eastern Pacific Ocean (tEPO) as part of the "Tropical Ocean tRoposphere Exchange of Reactive halogens and Oxygenated hydrocarbons" (TORERO) project are presented.

TL;DR: The CU AMAX-DOAS instrument as discussed by the authors uses solar stray light to detect and quantify multiple trace gases, including nitrogen dioxide (NO2), glyoxal (CHOCHO), formaldehyde (HCHO), water vapor (H2O), nitrous acid (HONO), iodine monoxide (IO), bromine monoxide(BrO), and oxygen dimers (O4) at multiple wavelengths (absorption bands at 360, 477, 577, 632 nm).
