Estimated peak geoelectric field strengths during a Carrington-class magnetic storm

This dataset presents modeled estimates of peak one-minute-resolution geoelectric-field strengths at 1,616 survey sites across the contiguous United States during a hypothetical Carrington-class magnetic storm. The values are derived using magnetometer time series and magnetotelluric impedance tensors. Each entry includes a most-likely value and a 68% confidence interval.
