Climatological Statistics of Extreme Geomagnetic Fluctuations With Periods From 1 s to 60 min

Abstract Using a global database of 125 magnetometers covering several decades, we present occurrence statistics for fluctuations of the horizontal geomagnetic field (dBh/dt) exceeding the 99.97th percentile (P99.97) for both ramp changes (Rn) and the root‐mean‐square (Sn) of fluctuations over perio...
