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.

Clouds in Assam cleared a little bit today which allowed us to see #Brahmaputra River which has been flowing in severe flood condition! (Brown area in middle)
With a width of almost a dozen km, even coarse res satellites could capture it clearly

Looks like fire is still raging in the Baghjan oil field..
Farmers in NW India are about to begin harvesting rice crop. #Aqua #MODIS NDVI for Sep historically largest this year--indicating a whooping crop prod>12 m tons. Given traditional crop residue burning practice, it means an intense fire season with ~16000 incidences in Oct & Nov

I will revise it with monthly observations once they are available (likely in 2nd week of Oct), however not expecting major change in results.
