The first #stratospheric #volcanic #eruption of 2022, at #HungaTongaHungaHaapai (#Tonga) on Jan 13-14. #Sentinel5P #TROPOMI & @NASA's Aura/OMI both measure ~0.05 Tg SO₂ in the #volcanic cloud - not enough for #climate impacts. @CopernicusEU @NASAEarth @volcanessa @MetService 
Another spectacular #eruption of Hunga #Tonga-Hunga Ha'apai at ~04:00 UTC on Jan 15. #Himawari8 data via @CIRA_CSU.
First look at SO₂ in the Jan 15 #eruption cloud measured by @eumetsat MetOp/GOME-2. So far, the SO₂ columns do not appear to be extreme; generally <20 Dobson Units (DU). For a Pinatubo-scale event we'd expect SO₂ columns >100 DU. More data soon.
