Parameter sensitivity maps of surface geoelectric arrays [PDF]
, 2006 Parameter sensitivity maps allow a better understanding of various geoelectric responses, and they are also helpful in designing optimal new arrays for specific problems. We constructed systematic parameter sensitivity maps for various geoelectric arrays,

Spatial Resolution Requirements for FDTD Modeling of Geoelectric Fields
Journal of Geophysical Research: Space PhysicsAbstractTo ensure the robustness of both civilian and military infrastructure, it is important to protect electric power grids, smart grids, and other electrotechnologies from known and possibly as‐of‐yet unknown space weather hazards. Space weather can generate intense geoelectric fields at the surface of the Earth, as well as large voltage gradients ...
