DOI: 10.1002/2017ja024362
Abstract: We investigate localized thermospheric neutral density increases (or density spikes) developed during the 24 August 2005 geomagnetic storm and utilize a multi-instrument database for monitoring the underlying thermospheric, ionospheric, magnetospheric, and solar wind conditions. We… read more here.

DOI: 10.1007/s00484-018-01657-y
Abstract: It has been suggested that geomagnetic storms could be perceived by organisms via disruption of naturally occurring diurnal geomagnetic variation. This variation, in turn, is viewed by way of a zeitgeber for biological circadian rhythms.… read more here.
