Terrestrial and space weather storm scales have a common shortcoming: The scales end at “5.” Nature of course doesn’t know this and sometimes produces a disturbance that is simply off the charts.
As part of the US National Space Weather Strategy and Action Plan, and following the 2016 Executive Order 13744, the Department of Defense (DoD) is now opening a more than 15-year record of GPS particle data to scientific scrutiny.
In The Conversation newsletter, scientists Delores Knipp and Brett Carter explore the significance of severe geomagnetic storm events and their impact on communications technology through descriptive historical accounts.
We perform the first ever global-scale, altitude-dependent analysis of polar ionospheric conductivity variability using spectrally-resolved in-situ satellite particle measurements. Our results show that height-integrated conductance and height-dependent conductivities are distinctly different.
Although listed as one of the most significant events of the last 80 years, the space weather storm of late May 1967 has been of mostly fading academic interest.
In a recent AGU editor's Vox Discussion, Delores Knipp explores the societal impacts of geomagnetically induced currents (GICs). GICs can cause voltage swings, transformer heating, and reactive power loss in high-voltage power transmission systems.
