TL;DR: In this paper , the authors synthesize satellite, ground-based, in situ and radiosonde observations of the Hunga Tonga-Hunga Ha-apai volcano to investigate the strength of the stratospheric aerosol and water vapour perturbations in the initial weeks after the eruption and quantify the net radiative impact across the two species using offline radiative transfer modelling.

TL;DR: The phase-locked cycles of lava lake convection and gas plume composition have been observed at Erebus volcano, Antarctica as discussed by the authors, and the observed fluctuations in gas ratios, including the SO2/CO2 content in the plume, identify two end-member contributions to the EREbus emission: a sustained source of CO2-rich gas percolating through permeable conduit magma, and a shallower source of H2O-rich gases exsolved from magma pulses that periodically enter the lava lake.

TL;DR: In this article, the authors use two wide field of view UV spectrometers capable of collecting light from thin parallel cross-sections of the whole gas plume, obviating the need for either traversing, scanning or imaging.

TL;DR: In this paper, the authors used acoustic measurements to interpret the Strombolian activity at Shishaldin volcano and found that the bubble does not burst at its maximum radius, as expected if the liquid film is stretched beyond its elasticity.
