TL;DR: Observations and model calculations together indicate that healing of the Antarctic ozone layer has now begun to occur during the month of September, and a chemically driven increase in polar ozone (or “healing”) is expected in response to this historic agreement.

TL;DR: In this article, a database of volcanic SO2 emissions and plume altitudes for eruptions from 1990 to 2014, and developed a new prognostic capability for simulating stratospheric sulfate aerosols in the Community Earth System Model (CESM).

TL;DR: Investigations of an Icelandic volcanic eruption confirm that sulfate aerosols caused a discernible yet transient brightening effect, as predicted, but their effect on the liquid water path was unexpectedly negligible.

TL;DR: In this article, the authors used lidar, Aerosol Robotic Network, and balloon-borne observations to provide evidence that currently available satellite databases neglect substantial amounts of volcanic aerosol between the tropopause and 15'km at middle to high latitudes and therefore underestimate total radiative forcing resulting from the recent eruptions.

TL;DR: In this paper, a global aerosol microphysics model together with a radiative transfer model was used to estimate radiative effects for five natural aerosol sources in the present-day atmosphere: dimethyl sulfide (DMS), sea-salt, volcanoes, monoterpenes, and wildfires.
