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.

An #eruption of #Nyiragongo #volcano (#DRC) began in the evening of May 22. #Meteosat satellite data (from @CIRA_CSU) show a strong thermal anomaly appearing at 17:15 UTC, and a small #volcanic plume amidst widespread regional convection. Follow @CharlesBalagizi for updates.
If you're looking for background info on #Nyiragongo and its previous flank #eruptions in 1977 and 2002, there's a collection of papers in the Italian Acta Vulcanologica journal available here (with free PDFs):

#Sentinel5P #Tropomi data on May 23 show SO₂ emissions from the #Nyiragongo #eruption. SO₂ to the SE over #Tanzania is at higher altitude (perhaps to tropopause level) and was emitted during the initial, more energetic phase of the eruption (17:00 UTC, May 22). @VirungaSupersit Image

Maritime traffic has a significative impact on #airpollution as ships🚢release #NOx & #CO2 etc. in the atmosphere
