DOI: 10.1029/2022gl099381
Abstract: Following the 15 January 2022 Hunga Tonga‐Hunga Ha'apai eruption, several trace gases measured by the Aura Microwave Limb Sounder (MLS) displayed anomalous stratospheric values. Trajectories and radiance simulations confirm that the H2O, SO2, and HCl… read more here.

DOI: 10.1029/2023gl107630
Abstract: The January 2022 eruption of Hunga Tonga‐Hunga Ha'apai (HTHH) injected a huge amount (∼150 Tg) of water vapor (H2O) into the stratosphere, along with small amount of SO2. An off‐line 3‐D chemical transport model (CTM)… read more here.

DOI: 10.1029/2024gl111983
Abstract: On 15 January 2022, a massive underwater eruption occurred at the Hunga Tonga‐Hunga Ha'apai Volcano. The plume reached the mesosphere, and the eruption excited a significant atmospheric Lamb wave, which forced the tsunami. The complicated… read more here.

DOI: 10.1029/2025gl115294
Abstract: Atmospheric Lamb waveforms are useful for reconstructing large air events, but the propagation of Lamb waves is significantly affected by varying atmospheric conditions. The detailed dispersion of Lamb waves remains vague due to lack of… read more here.
