Michelson Interferometer for Global High-resolution Thermospheric Imaging (MIGHTI) on the …

The eruption of the Hunga Tonga‐Hunga Ha'apai volcano on 15 January 2022 triggered
atmospheric waves at all altitudes. The National Aeronautics and Space Administration …

This paper investigates the local and global ionospheric responses to the 2022 Tonga

Abstract Following the 2022 Tonga Volcano eruption, dramatic suppression and deformation
of the equatorial ionization anomaly (EIA) crests occurred in the American sector∼ 14,000 …

The wind shear theory is widely accepted as an explanation for the formation of a sporadic E
(Es) layer, but the direct comparison of Es with the local wind shear has been limited due to …

We present space‐and ground‐based multi‐instrument observations demonstrating the
impact of the 2022 Tonga volcanic eruption on dayside equatorial electrodynamics. A strong …

We discuss, in a limited way, some of the challenges to advancing our understanding and
description of the coupled plasma and neutral gas that make up the ionosphere and …

The two-year prime mission of the NASA Ionospheric Connection Explorer (ICON) is
complete. The baseline operational and scientific objectives have been met and exceeded …

We compare coincident thermospheric neutral wind observations made by the Michelson
