Stratospheric NO2 and NO3 observations by the Stratospheric Aerosol and Gas Experiment (SAGE III/ISS) in the wake of the Hunga Tonga - Hunga Ha’apai eruption
David E Flittner + Kevin Leavor + Robert Manion
The powerful eruption of the Hunga Tonga – Hunga Ha’apai (HTHH) caldera directly injected into the stratosphere a tremendous volume of water (in multiple phases) and a modest...
AGU23 | 25 January 2024
Stratospheric impacts of the Hunga-Tonga Aerosol Perturbation
Eric L Fleming + Ghassan Taha + Luke Oman ...
The Hunga-Tonga eruption in January 2022 injected water vapor and sulfur dioxide (SO2) into the mid-stratosphere, with the SO2 rapidly converted into sulfate aerosol particles....
AGU23 | 15 December 2023
Ionospheric disturbance of the 2022 eruption of Hunga Tonga-Hunga Ha’apai measured by GNSS
Yosuke Aoki
An explosive eruption of Hunga Tonga-Hunga Ha'apai on 15 January 2022 at around 4:00 UTC disturbed the ionosphere, as well as the atmosphere. We observed the ionospheric disturbance...
AGU23 | 14 December 2023
Temporal and spatial transport of the Hunga-Tonga Hunga-Ha’apai water vapor plume investigated by satellite observation and model simulations
Sandra Wallis + Christian von Savigny + Claudia Timmreck ...
On January 15, 2022 the Hunga-Tonga Hunga-Ha’apai volcano emitted sulfate dioxide and an exceptionally large amount of approximately 146 Tg water vapor into the middle atmosphere....

The Estimated Climate Impact of the Hunga Tonga-Hunga Ha’apai Eruption Plume
Mark R Schoeberl + Andrew E Dessler + Ghassan Taha ...
On Jan. 15, 2022, the Hunga Tonga-Hunga Ha’apai (HT) eruption injected SO2 and water into the middle stratosphere. The SO2 is rapidly converted to aerosols. The aerosol and...
