Another major #eruption of #Ruang. Geostationary UV #GK2B GEMS data nicely capture the spreading #volcanic SO₂ cloud, including the #stratospheric overshoot drifting rapidly westwards. The SO₂ mass (~0.3 Tg) is very preliminary and needs confirmation from other sensors.
@eddy_weather@highlandweather That's right, there's no chance that the Icelandic SO₂ emissions are impacting recent Scottish weather. Magnitude and altitude both far too low.
Longer sequence of hourly #GEMS data (daytime only) showing SO₂ emissions from the June 3 #Kanlaon#eruption. On June 5, the upper tropospheric SO₂ cloud was moving west over #SriLanka and S. #India, whilst SO₂ at lower altitudes is dispersing over the southern #Philippines.
@HubGeology@phivolcs_dost@News5PH@nababaha I think this is the first #Kanlaon eruption in the satellite era to produce a significant amount of SO₂ (more than a few kilotons). The November 2023 #Ulawun eruption emitted ~0.1 Tg SO₂.

@eddy_weather@ThePurpleAir@DefraGovUK Many thanks Eddy - great to have some observations from the ground. The SO₂ amounts were quite impressive, but luckily this was a relatively short-lived episode.
@Weather_West@GOESguy Satellite observations are somewhat variable but suggest a total of ~0.6-1.5 Tg SO₂ emitted by the two #eruptions. Even at the high end, this is below the ~5 Tg threshold for measurable #climate impacts.
