The January 2022 eruption of Hunga Tonga-Hunga Ha’apai (HTHH) injected a huge amount (~150 Tg) of water vapour (HO) into the stratosphere, along with small amount of SO. An off-line 3-D chemical transport model (CTM) successfully reproduces the spread of the injected HO through October 2023 as obser...
