TL;DR: In this paper, the authors simulate the record of sulfur mass independent fractionation (MIF) in sulfates found in the Antarctic ice cores from the 1991 eruption of Mt Pinatubo and show that a time-dependent non-zero sulfur MIF can be delivered to the ground in the present atmosphere if the MIF-producing process is SO3 photolysis Fractionation from such photolyisation has not been considered before, but is consistent with the available experimental data.

TL;DR: In this article, a pre-study experiment with interactive stratospheric aerosol models simulating the volcanic aerosol cloud from an eruption resembling the 1815 Mt. Tambora eruption (VolMIP-Tambora ISA ensemble).

TL;DR: In this article, the authors used an Aerosol Mass Spectrometer (AMS) to examine the chemical structure of Titan haze particles under a variety of starting conditions in real-time and without collection.

TL;DR: In this article, the authors consider explanations for disagreements between models and measurements of clear-sky solar transmission and study data from four cloud-free days during the FIRE 1991 field experiment.

TL;DR: In this article, a new three dimensional GCM with a complete microphysics treatment of the aerosols was presented, which was validated by comparing the extinction, optical depth, phase functions, and number densities with data from Cassini and Huygens, as well as other space based and ground based observations.
