Impact of the Hunga Tonga volcanic eruption on stratospheric composition [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2023
The explosive eruption of the Hunga Tonga-Hunga Ha’apai (HTHH) volcano on 15 January 2022 injected more water vapor into the stratosphere and to higher altitudes than ever observed in the satellite era. Here, the evolution of the stratospherically injected water vapor is examined as a function of latitude, altitude, and time in the year ...
