Researchers reveal disturbances of Tonga volcanic eruption

Recently, a team led by Prof. Lei Jiuhou from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences and the collaborators revealed the notable evidence of the dramatic thermospheric disturbances and global upper thermospheric perturbations of the Tonga eruption (January 15, 2022), and confirmed that the impact of volcanic eruption has outreached the ionosphere and creeps into the thermospheric density up to 500 km satellite orbiting altitudes. This study was published in Geophysical Research Letters.
