Role of heterogeneous conversion of N2O5 on sulphate aerosols in global ozone losses
TL;DR: In this paper, the reaction rate of N2O5 on sulphate aerosols is included in a model to predict global ozone loss and the column abundances of atmospheric gases, and the decadal ozone trends resulting from calculations based on the model are found to be closer to the observed values.
Journal ArticleDOI
Are antarctic ozone variations a manifestation of dynamics or chemistry
TL;DR: The existence of a reverse circulation cell with rising motion in the polar lower stratosphere is suggested as an explanation for the temporal behavior of the ozone column density in the Antarctic region as discussed by the authors.
Journal ArticleDOI
A two‐dimensional model of sulfur species and aerosols
Debra K. Weisenstein,Glenn K. Yue,Malcolm K. W. Ko,Nien Dak Sze,Jose M. Rodriguez,Courtney J. Scott +5 more
TL;DR: In this article, a two-dimensional model of sulfate aerosols has been developed, which includes the sulfate precursor species H2S, CS2, DMS, OCS, and SO2.
Journal ArticleDOI
Anthropogenic CO Emissions: Implications for the Atmospheric CO-OH-CH4 Cycle
TL;DR: Present anthropogenic emissions of CO are apparently large enough to perturb the natural CO-OH-CH4 cycle, which plays a crucial role in the self-cleansing processes in the troposphere and may also indirectly affect stratospheric chemistry.
Global Simulation of Atmospheric Mercury Concentrations and Deposition Fluxes. Appendix Q
TL;DR: In this article, a numerical model of the global emissions, transport, chemistry, and deposition of mercury (Hg) in the atmosphere is presented, which shows that aqueous chemistry is an essential component of the atmospheric cycling of Hg.
