Abstract:Modern society depends heavily on a variety of technologies that are vulnerable to the effects of intense geomagnetic storms and solar energetic particle (SEP) events. Strong currents flowing in the ionosphere can disrupt and damage Earth-based electric power grids and contribute to the accelerated corrosion of oil and gas pipelines. Magnetic storm-driven ionospheric disturbances interfere with high-frequency radio communications and navigation signals from Global Positioning System (GPS) satellites. Exposure of spacecraft to solar particles and radiation belt enhancements can cause temporary operational anomalies, damage critical electronics, degrade solar arrays, and blind optical systems such as imagers and star trackers. A complete picture of the socioeconomic impact of severe space weather must include both direct as well as collateral effects of space-weather-driven technology failures on dependent infrastructures and services. This talk describes our continuing efforts to understand space weather and assess its consequences for human technological systems.
