abstract = {On 15 January 2022, the Hunga Tonga–Hunga Ha'apai volcano
erupted violently. This exceptional event excited a manifold
of atmospheric waves. Here, we focus on the mesoscale part
of the wave spectrum. About 8.5 hr after the eruption a
strong atmospheric gravity wave (GW) was observed in the
stratosphere by the satellite instruments Atmospheric
Infrared Sounder (AIRS) and Microwave Limb Sounder (MLS) in
the vicinity of Tonga. By ray-tracing, we confirm the
eruption as the source of this GW event. We determine the
wave characteristics of the GW in terms of horizontal and
vertical wavelengths and GW momentum flux. The strength of
the GW is compared to the usual Southern Hemisphere flux
values during this week. The event is comparable to the
strongest convective events considering MLS, and
exceptionally strong considering AIRS, which observes faster
waves only.},
