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: In this article , a combination of space-borne instruments were used to study the unprecedented stratospheric plume after the Tonga eruption of 15 January 2022, which was initially formed of two clouds at 30 and 28 km, mostly composed of submicron-sized sulfate particles.

TL;DR: In this article , a balloon-borne characterization of the stratospheric aerosol plume one week after its injection (on 23 and 26 January 2022, La Réunion island at 21.1°S, 55.3°E) is presented.

TL;DR: In this paper , the authors used a combination of space-borne instruments to study the unprecedented stratospheric plume after the Hunga Tonga eruption of 15 January 2022, which was formed of two initial clouds at 30 and 28 km mostly composed of sub-micronic sulphate particles without ashes, washed-out within the first hours.

TL;DR: In this article , the authors focus on the high quality data series of SAGE III/ISS to determine the mean radius and size distribution of the aerosols and their total mass and show that the persisting aerosols are expected to induce a small negative aerosol radiative forcing, thus facilitating the persistence of a climate warming due to the volcanic water vapour.
