In this new paper, the 2022 Hunga eruption's Lamb wave was found to have led to an unexpected cloud darkening ~12,000 km from the volcano.๐โ๏ธ
The paper was included in the recent Nature research highlights:

In this #OpenAccess paper, a new retrieval approach for obtaining aerosol extinction profiles from OMPS-LP measurements is presented. Sun normalization makes it better suited for highly elevated aerosol plumes, e.g. after the Hunga eruption.

Pohl et al. improved a method to obtain stratospheric aerosol sizes and extinction coefficients from SCIAMACHY limb observations. This data set expands our limited knowledge of stratospheric aerosol properties. ๐๐ฐ๏ธ๐ป

In this new paper, Horvรกth et al.(2024) track Lamb and gravity waves generated by the 2022 #HungaTonga eruption using 1-minute resolution GOES-R mesoscale images, revealing the fine structure of the waveforms not seen in the lower cadence full disk images!

In this recent paper Niemeier et al. (2023) could accurately reproduce the transport of the water vapor injected by the ๐๐ฎ๐ง๐ ๐ ๐๐จ๐ง๐ ๐ eruption for over 1,5 years with a free running model simulation of ICON-Seamless!

I've posted loads of still images of Anak Krakatau's explosive activity over the past couple of days. Now we get to see it in moving pictures (showing my age there). What an incredible sight ๐

New paper on Hunga Tonga eruption freshly published: "Observation of the Aerosol Plume From the 2022 Hunga TongaโHunga Ha'apai Eruption With SAGE III/ISS"
Please download it here, it is open access --> agupubs.onlinelibrary.wiley.โฆ
@IPSL_outreach @LISA_ipsl @UPECactus @Geosciences_ENS
In this new paper Wrana et al. show, that some volcanic eruptions lead to an unexpected strong and long-lasting decrease in stratospheric aerosol size!๐The SAGE III/ISS based results are then compared to model simulations with the MAECHAM5-HAM model. ๐ฐ๏ธ๐ป

It doesnโt have to be a Hunga-Tonga! Even when neglecting direct water injections, both non-frozen and frozen moisture fluxes into the stratosphere are enhanced after volcanic eruptions. ๐โ๏ธ

All the way up! How do strong volcanic eruptions impact the temperature in the summer mesosphere?
