Large Geomagnetically Induced Current Events and Storm Relationships, 1999-2020

Finnish natural gas pipeline measurements from 1999 to 2020 provide the basis for this dataset. It contains 81 large geomagnetically induced current (GIC) disturbance events identified from high-resolution 10-second data at the Mäntsälä compressor station. The data, authored by Wenjin Zhao, statistically relates these events to 39 intense geomagnetic storms and their interplanetary drivers.

Use Cases

• Modeling the relationship between geomagnetic storm intensity and GIC magnitude based on the described statistical analysis.
• Identifying interplanetary drivers of GIC events based on the reported prevalence of interplanetary coronal mass ejections (ICMEs).
• Assessing GIC risk from moderate and weak geomagnetic storms based on the finding that 14 events were associated with such storms.

Strengths

• Covers nearly two solar cycles (1999-2020), providing long-term context.
• Based on high-resolution 10-second measurement data.
• Includes 81 systematically identified large GIC events linked to 39 intense storms.

Limitations

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