TL;DR: In this article , the authors employed continuous sulfate and sulfur records from three Greenland and three Antarctic ice cores to estimate the emission strength, the frequency and the climatic forcing of large volcanic eruptions that occurred during the second half of the last glacial period and the early Holocene, 60-9 kyr before 2000 CE (b2k).

TL;DR: The HolVol v.1.0 database includes estimates of the magnitudes and approximate source latitudes of major volcanic stratospheric sulfur injection events for the Holocene (from 9500 BCE or 11 500 years BP to 1900 CE) as mentioned in this paper .

TL;DR: In this article , the optical properties of surface aerosols at Dome C, Antarctica, in 2007-2013 and their potential source areas were presented, where the authors measured particle number size distributions with a Mie code and from filter samples using mass scattering efficiencies.

TL;DR: In this article , the data from 17 urban monitoring sites in Tuscany are presented, and the PM and NO2 concentrations in the 2 months before the start of the lockdown and 2 months after lockdown are compared with the corresponding months of the previous 3 years, showing that the total loads of PM2.5 and PM10 decreased, but they did not exhibit significant changes compared to previous years, whereas NO2 underwent a drastic reduction.

TL;DR: In this paper , the authors assess the frequency at which volcanic eruptions with particular deposition fluxes are observed in the EPICA Dome C ice core over the last 200 kyr and confirm that most of the largest peaks recorded at Dome C are from stratospheric eruptions.
