Journal ArticleDOI
Variability in morphology, hygroscopicity, and optical properties of soot aerosols during atmospheric processing
TL;DR: Experimental studies are presented to show that soot particles acquire a large mass fraction of sulfuric acid during atmospheric aging, considerably altering their properties, representing an important mechanism of atmospheric aging.
Journal ArticleDOI
A study of type I polar stratospheric cloud formation
TL;DR: In this paper, a unique nucleation mechanism that involves formation of HNO3/H20 solutions on the sulfate ice particles was proposed, resulting in the formation of a relatively small number of large particles.
Journal ArticleDOI
Formation of highly hygroscopic soot aerosols upon internal mixing with sulfuric acid vapor
Alexei F. Khalizov,Renyi Zhang,Dan Zhang,Huaxin Xue,Joakim Pagels,Joakim Pagels,Peter H. McMurry +6 more
TL;DR: In this article, a combined tandem differential mobility analyzer (TDMA) and differential mobility analysis (DMA-APM) technique was used to investigate the hygroscopic properties of submicron soot particles during internal mixing with gaseous sulfuric acid.
Journal ArticleDOI
Modeling the composition of liquid stratospheric aerosols
TL;DR: This paper reviewed thermodynamic models of the liquid phase that enable the partitioning of gases such as HCl, HBr, HOCl, and HNO3 into sulfuric acid aerosols to be calculated over the full range of stratospheric conditions.
Journal ArticleDOI
A model for studying the composition and chemical effects of stratospheric aerosols
TL;DR: In this article, the authors developed polynomial expressions for the temperature dependence of the mean binary and water activity coefficients for H2SO4 and HNO3 solutions, which were used in an equilibrium model to predict the composition of stratospheric aerosols under a wide range of environmental conditions.

Physical chemistry of the sulfuric acid/water binary system at low temperatures: stratospheric implications
TL;DR: In this paper, the physical chemistry of the H2SOd/H20 binary system under conditions characteristic of the stratosphere was investigated and the results indicated that some of the hydrates of sulfuric acid may form and persist under the temperature and water partial pressure conditions typical of the high-latitude stratosphere.
