Abstract Following the 15 January 2022 Hunga Tonga‐Hunga Ha'apai eruption, several
trace gases measured by the Aura Microwave Limb Sounder (MLS) displayed anomalous …

Volcanic eruptions can be catastrophic events, particularly when they occur in inhabited
coastal environments. They also play important roles in climate and biogeochemical cycles …

Abstract The underwater Hunga Tonga-Hunga Ha-apai volcano erupted in the early hours of
15th January 2022, and injected volcanic gases and aerosols to over 50 km altitude. Here …

We use a combination of spaceborne instruments to study the unprecedented stratospheric
plume after the Tonga eruption of 15 January 2022. The aerosol plume was initially formed …

Global mean lower stratosphere temperatures rose abruptly in January 2020 reaching
values not experienced since the early 1990s. Anomalously high lower stratospheric …

Abstract The Tonga eruption of 15 January 2022 has released a long‐lived stratospheric
plume of sulfate aerosols. More than 17 months after, we focus on the high quality data …

Raikoke, a small, unmonitored volcano in the Kuril Islands, erupted in June 2019. We
integrate data from satellites (including Sentinel-2, TROPOMI, MODIS, Himawari-8), the …

Abstract During spring 2020, the COVID-19 pandemic caused massive reductions in
emissions from industry and ground and airborne transportation. To explore the resulting …

Uncertainty-bounded satellite retrievals of volcanic ash cloud properties such as ash cloud-
top height, effective radius, optical depth and mass loading are needed for the robust …

Recent research has provided evidence of the self-lofting capacity of smoke aerosols in the
stratosphere and their self-confinement by persistent anticyclones, which prolongs their …
