The 2019 Raikoke eruption as a testbed for rapid assessment of volcanic atmospheric impacts by the Volcano Response group

Abstract: Abstract. The 21st June 2019 Raikoke eruption (48° N,153° E) generated one of the largest amounts of sulfur emission to the stratosphere since the 1991 Mt Pinatubo eruption. Satellite measurements indicate a consensus best estimate of 1.5 Tg for the sulfur dioxide (SO2) injected at an altitude of around 14–15 km. The peak northern hemisphere mean 525 nm Stratospheric Aerosol Optical Depth (SAOD) increased to 0.025, a factor of three higher than background levels. The Volcano Response (VolRes) initiative provid… Show more

“…The joint interpretation of satellite and ground-based remote sensing observations of the HT-HH plume, as well as multi-station data analysis, are performed using the VOLCPLUME interactive web portal (Boichu & Mathurin, 2022), that was used in crisis time to deliver information on HT-HH aerosols (Vernier et al, 2022;Lac et al, 2022). The explosive eruption of HT-HH starts on 15 January 2022 around 04:00 UTC (Fig.…”
