Addressing space weather needs in a technology dependent society

Disturbances from the Sun often referred to as “space weather”, cause geomagnetic storms that can affect critical infrastructure on the ground such as navigation systems, high-voltage electric power transmission grids, and pipelines. Understanding the dynamic response of the coupled solar wind-magnetosphere-ionosphere system to severe space weather is an on-going challenge. This talk will highlight some of my past and on-going applied space weather research efforts and how this information can be used to address societal needs. More specifically, the talk will focus on studies of geomagnetically induced currents (GICs), and ionospheric disturbances that manifest as perturbations in the electron density of the ionosphere.
