The January 2022 eruption of Hunga Tonga-Hunga Ha’apai volcano reached the mesosphere

open access: yesScience, 2022
Explosive volcanic eruptions can loft ash, gases, and water into the stratosphere, which affects both human activities and the climate. Using geostationary satellite images of the 15 January 2022 eruption of the Hunga Tonga-Hunga Ha’apai volcano, we find
