Empirical Relationship for Geomagnetically Induced Currents (GIC) and Solar Wind Conditions
Dean Thomas, Lucy A. Wilkerson, Robert S. Weigel +2
Geomagnetically induced currents (GICs) during extreme space weather events represent a critical hazard to modern infrastructure, including electrical power grids, telecommunicatio…
A Comparative Multi-Hazard Risk Assessment of the US High-Voltage Transmission Network
D. Bor, E. J. Oughton, R. S. Weigel +4
Modern economies depend critically on high-voltage power transmission networks. Yet this infrastructure is routinely disrupted by natural hazards ranging from earthquakes and flood…
C-SWIM: A Coupled Space Weather Impact Model for Satellite Fleet Vulnerability and Economic Loss Under a 1-in-100-Year Solar Energetic Particle Event
D. Bor, E. J. Oughton, R. S. Weigel +4
Modern economies depend critically on satellite infrastructure, yet the aggregate economic consequences of extreme solar energetic particle (SEP) events have not been rigorously as…
Brace for Impact: A Review of Mitigation Decisions of Critical Infrastructure Operators During the 2024 Solar Maximum
Caitlin LaNeve, Edward J Oughton, Noah Rivera +4
The Gannon Storm in May 2024 was the largest space weather event experienced in 20 years, generating auroras latitudes as low as 35°. Such activity can pose significant operational…
Major Space Weather Risks Identified via Coupled Physics-Engineering-Economic Modeling
Edward J. Oughton, Dennies K. Bor, Robert Weigel +5
Space weather poses an important but under-quantified threat to society. While severe geomagnetic storms are recognized as potential global catastrophes, their socio-economic impac…
A Reproducible Method for Mapping Electricity Transmission Infrastructure for Space Weather Risk Assessment
Dennies K. Bor, Edward J. Oughton, Evan A. Peters +4
Space weather risk assessment is constrained by the lack of available asset information needed to model geomagnetically induced currents (GICs) in electricity transmission infrastr…
