A compilation of tropospheric measurements of gas-phase and aerosol chemistry in polar regions [PDF]

Earth System Science Data, 2012
Measurements of atmospheric chemistry in polar regions have been made for more than half a century. Probably the first Antarctic ozone data were recorded in 1958 during the International Geophysical Year.

Lookup tables to compute high energy cosmic ray induced atmospheric ionization and changes in atmospheric chemistry

, 2010
A variety of events such as gamma-ray bursts and supernovae may expose the Earth to an increased flux of high-energy cosmic rays, with potentially important effects on the biosphere. Existing atmospheric chemistry software does not have the capability of

Ions at the air-water interface: An end to one hundred year old mystery? [PDF]

, 2009
Availability of highly reactive halogen ions at the surface of aerosols has tremendous implications for the atmospheric chemistry. Yet neither simulations, experiments, nor existing theories are able to provide a fully consistent description of the ...

Improvement in Modeling of OH and HO₂ Radical Concentrations during Toluene and Xylene Oxidation with RACM2 Using MCM/GECKO-A

Atmosphere, 2021
Due to their major role in atmospheric chemistry and secondary pollutant formation such as ozone or secondary organic aerosols, an accurate representation of OH and HO2 (HOX) radicals in air quality models is essential.

The Atmospheric Chemistry of GJ 1214b: Photochemistry and Clouds [PDF]

, 2011
Recent observations of the transiting super-Earth GJ 1214b reveal that its atmosphere may be hydrogen-rich or water-rich in nature, with clouds or hazes potentially affecting its transmission spectrum in the optical and very-near-IR.
