In this paper, Sun-photometer multichannel measurements of aerosol optical depths (AODs) in the visible and near-infrared spectral ranges, and Angstrom parameters of the plume issued from the Pacaya volcano, Guatemala, are presented for the first time These observations, made during a short-term campaign carried out on 29 and 30 January 2011, indicate a diluted (AODs lower than 01) volcanic plume composed of small particles (Angstrom exponent ∼10 on 29 January and ∼14 on 30 January) Results are consistent with an ash-free plume Finally, the impact of the choice of different wavelength pairs for the calculation of the Angstrom parameters from the spectral AOD observations is tested and critically discussedread more

TL;DR: In this article, the authors investigated the influence of the 2015 Calbuco eruption on the total columnar aerosol optical properties over the Southern Hemisphere and found that the majority of the plume was transported over the northeastern parts of South America and reached the South African region 1 week after the eruption.

Climatology of Aerosols over the Caribbean Islands: Aerosol Types, Synoptic Patterns, and Transport
TL;DR: In this paper , a climatological study of aerosols in four representative Caribbean Sea islands is presented, based on daily mean values of aerosol optical properties for the period 2008-16, using the aerosolic optical depth (AOD) and Ångström exponent (AE) to classify the dominant aerosol type.

Atmospheric effects of the Mt Pinatubo eruption
TL;DR: The eruption of Mt Pinatubo in June 1991 caused the largest perturbation this century to the participate content of the stratosphere, which put an end to several years of globally warm surface temperatures as discussed by the authors.

The effects of volcanic eruptions on atmospheric chemistry
TL;DR: In this paper, the main effects of volcanic emissions on atmospheric chemistry are discussed, with a focus on sulphur and halogen compounds, and to a smaller extent on climate, mainly focusing on quiescent degassing, but the main effect of explosive eruptions on the troposphere and stratosphere are covered as well.
