The National Science Foundation awarded a $419,448 Project Grant under its Geosciences program (CFDA 47.050) to the University of California, Los Angeles (UCLA) to conduct research on understanding the causes of geomagnetic disturbances (GMDs) and their impact on critical infrastructure. The key objectives are to:

  1. Expand the application of the Spherical Elementary Current System (SECS) method to analyze GMDs observed by ground magnetometers in North America and Greenland, in order to estimate the spatiotemporal variations of equivalent ionospheric and telluric currents.

  2. Evaluate the frequency of occurrence where the rate of change of the magnetic field (dB/dt) associated with ionospheric and telluric currents exceeds critical thresholds for potential damage to power grids, pipelines, and other infrastructure.

  3. Conduct event studies using data from THEMIS all-sky imagers, THEMIS and GOES spacecraft, and Space Weather Modeling Framework (SWMF) simulations to understand the driving mechanisms and development of space weather-induced GMDs.

The 3-year project period runs from July 1, 2024 to June 30, 2027 and will be conducted solely by the UCLA Office of Research Administration division at their facilities in Los Angeles, California.
