Short summary
The 2022 Hunga Tonga – Hunga Ha'apai eruption emitted about 150 Tg H2O that partly reached the upper polar Southern Hemisphere mesosphere in the beginning of 2024. Noctilucent clouds (NLCs) did not show a clear perturbation in their occurrence frequency, but the slight increase from mid-January to February could potentially have been caused by the additional H2O. It needed 2 years to reach the summer polar mesopause region, analogous to the 1883 Krakatoa eruption that is argued to have caused the first sightings of NLCs.
