Ionospheric Disturbance Data from the 2022 Tonga Eruption and Tsunami

The Southwestern Pacific region is the focus of this dataset containing filtered ionospheric total electron content values. It was used in a scientific manuscript authored by Jessica N Ghent of the University of Washington, analyzing the effects of the January 15, 2022 Tonga eruption and tsunami. The dataset's specific size and temporal range are not detailed in the provided metadata.

Use Cases

• Modeling ionospheric perturbations based on total electron content values
• Analyzing the spatial propagation of disturbances from a volcanic eruption
• Studying tsunami-induced atmospheric gravity waves using ionospheric data
• Correlating terrestrial natural disasters with upper atmospheric phenomena

Strengths

• Data is directly linked to a specific, significant geophysical event (the January 15, 2022 Tonga eruption)
• Associated with a peer-reviewed scientific manuscript, suggesting research-grade curation
• Authored by a researcher from a known academic institution (University of Washington)

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Last update date is unknown; freshness unverified
