Assimilation of Ground and Satellite Magnetic Observations Unravels the Ionospheric, Magnetospheric, and Induced Fields During the May and October 2024 Geomagnetic Storms

open access: yesGeophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract The geomagnetic storms of May and October 2024 were the strongest storms of solar cycle 25, with the Dst $Dst$ index as low as −412 nT and auroras down to low latitudes. To investigate these extreme events, we developed a global magnetic field model of magnetospheric, ionospheric, and Earth‐induced contributions obtained by assimilating ...

On reduced-order filter design for uncertain cascaded 2-1 sigma-delta modulators [PDF]

open access: yes, 2011
In this paper, we present a new robust matching filter design method for uncertain 2-1 cascaded sigma-delta modulators. This method addresses a well known limitation of H-infinity loop shaping techniques that they yield filters of high order (equal to ...
