Global Propagation of Ionospheric Disturbances Associated With the 2022 Tonga Volcanic Eruption

David R. Themens et al.

Summary: This study uses measurements from globally distributed Global Navigation Satellite System receivers to track the progression of traveling ionospheric disturbances (TIDs) associated with the eruption of the Hunga Tonga-Hunga Ha'apai submarine volcano. The results demonstrate the global impact of the Tonga eruption on the ionospheric state.

Rapid Characterization of Large Volcanic Eruptions: Measuring the Impulse of the Hunga Tonga Ha'apai Explosion From Teleseismic Waves

Piero Poli et al.

Summary: Most volcanic activity occurs in remote areas, making our monitoring capacity limited. This study presents a method based on seismic analysis to rapidly identify and estimate key parameters of large volcanic eruptions. The analysis of the Hunga Tonga Ha'apai eruption indicates that it is among the largest recorded volcanic activity and provides new insights into the physics of large eruptions.

2022 Tonga Volcanic Eruption Induced Global Propagation of Ionospheric Disturbances via Lamb Waves

Shun-Rong Zhang et al.

Summary: The study provides a global perspective on the ionospheric disturbances caused by the Tonga volcano eruption. Using ionospheric measurements from over 5,000 GNSS ground receivers worldwide, the study reveals the radial outbound and inbound traveling ionospheric disturbances following the eruption. These disturbances propagate globally and follow the effect of Lamb waves, suggesting the leakage of energy from Lamb waves into the ionosphere.

NRLMSIS 2.0: A Whole-Atmosphere Empirical Model of Temperature and Neutral Species Densities

J. T. Emmert et al.

Summary: NRLMSIS* 2.0 is an empirical atmospheric model that extends from ground to exobase, describing temperature and species densities of atmosphere based on location, time, solar and geomagnetic activities. The upgraded model shows improved accuracy in certain layers while also lowering species densities in the thermosphere.

Locating surface deformation induced by earthquakes using GPS, GLONASS and Galileo ionospheric sounding from a single station

Florian Zedek et al.

Summary: The study evaluates the capability of a single GNSS station to constrain the origin location of coseismic ionospheric disturbances (CID) through observations of Total Electron Content (TEC). It confirms that increasing the number of monitoring satellites helps in resolving CID origins. By using TEC data from earthquakes of different moment magnitudes, the research shows that a well-placed multi-GNSS station can accurately retrieve the origin of CID with a high level of precision.

Correlation Between GNSS-TEC and Eruption Magnitude Supports the Use of Ionospheric Sensing to Complement Volcanic Hazard Assessment

Fabio Manta et al.

Summary: This study explores the use of GNSS to measure ionospheric total electron content (TEC) perturbations to complement traditional volcano monitoring systems. A new metric, the Ionospheric Volcanic Power Index (IVPI), is introduced to quantify the energy transferred to the ionosphere by volcanic explosions. Results indicate that IVPI correlates well with the Volcanic Explosivity Index (VEI) and could potentially improve continuous volcano monitoring and warning systems through remote sensing.

International Geomagnetic Reference Field: the thirteenth generation

P. Alken et al.

Summary: The IAGA V-MOD working group adopted the thirteenth generation of the IGRF in December 2019, which includes definitive main field models for epoch 2015.0 and 2020.0, as well as predictive linear secular variations for 2020.0 to 2025.0. This update provides equations, spherical harmonic coefficients, and maps for magnetic parameters and their predicted changes from 2020.0 to 2025.0.
