Workshop outline:
The January 2022 Hunga Tonga–Hunga Haʻapai (HTHH) eruption was the most explosive volcanic eruption in the satellite era, and the water-rich plume is causing substantial impacts on the stratosphere and climate.
A SPARC cross-activity HTHH impacts project has convened a special Hunga-Tonga impacts report for publication in late-2025. The report will feed into the 2026 UNEP/WMO Scientific Assessment of Ozone Depletion, providing a benchmark synthesis of the eruption’s impacts on the stratosphere and climate.
This 2nd open science workshop invites latest research on Hunga-Tonga’s impacts on the atmosphere, with modelling and observational studies of the eruption itself, the progressing volcanic aerosol and water vapour and impacts on climate and the stratospheric ozone layer.
