We announce to the community a recently published paper on the identification of the different magnetic field contributions during a geomagnetic storm in magnetospheric and ground observations. The authors of the paper are SWICo members from different institutions.
Abstract:
We investigate the time variation of the magnetospheric and Earth’s magnetic field during both quiet and disturbed periods. We identify the timescale variations associated with different magnetospheric current systems, solar-wind–magnetosphere high-frequency interactions, ionospheric processes, and internal dynamics of the magnetosphere. In addition, we propose a new local index for the identification of the intensity of a geomagnetic storm on the ground.
