SWPC is pleased to announce that the experimental, one-dimensional, interpolated Geoelectric Field model became publicly available on November 02, 2017, and is available at http://www.swpc.noaa.gov/products/experimental-geoelectric-field-1-minute. This model is the result of a tri-agency effort between NOAA/SWPC, the USGS Geomagnetism Group, and NASA CCMC. It combines information about ground level, time-varying magnetic fields together with available one-dimensional Earth-conductivity information to estimate regional geoelectric field levels on a 2 x 2 degree geographic grid over the lower 48 states. The Geoelectric Field model provides near-real time estimates of the induction hazard to artificial conductors that result from geomagnetic activity. More details on this model are available at the web page listed above.
