Abstract

Geomagnetic disturbances have caused wide spread disruptions to power grids throughout North America. It is necessary to fully describe the complex physical manifestation of geomagnetic disturbance environments to model how and to what extent these disturbances impact modern ground-based critical infrastructures. The Ground Level Assimilative Model (GLAM) would provide the general public and operators of land-based infrastructures concerned about GIC impacts a set of geomagnetic storm climatology data in a context that can be readily used in power network models or other infrastructure models. The development would provide a meso-scale resolution geomagnetic storm data. The aspects of the work proposed for Phase 1 can be summarized as follows: Develop, test, and select high-cadence nowcast assimilative model of geomagnetic storm conditions over local and North American continental regions.
