New preprint on Essoar: "Balloon-borne observations of acoustic-gravity waves from the 2022 Hunga Tonga eruption in the stratosphere" where we analyze volcanic infrasound recorded at 20 km altitude, thousands of kms away from the volcano essoar.org/doi/10.1002/es…

Round-the-Earth #HungaTongaHungaHaapai infrasounds have been recorded by #Strateole2 balloons in the stratosphere several times on days following the eruption! @CNES @INSU_CNRS @IPSL_outreach @ISAE_officiel @esa_aeolus

Evidence of #HungaTonga volcanic plume sections as high as 40 km altitude. @IPSL_outreach @LISA_ipsl @UPECactus @FST_UPEC @INGVvulcani (CALIOP data for 15/1, upper panel; HIMAWARI data, lower panel - to geographically localise the CALIOP overpass; figure elaborated by B. Legras)

#Strateole2 balloon records of #HungaTongaHungaHaapai eruption on Jan. 15th. Impressive infrasound signals in the stratosphere! @CNES @INSU_CNRS @IPSL_outreach @ISAE_officiel @esa_aeolus
