Ionospheric control of space weather [PDF]

Annales Geophysicae, 2021
As proposed by Saka (2019), plasma injections arising out of the auroral ionosphere (ionospheric injection) are a characteristic process of the polar ionosphere at substorm onset.

Review of ionospheric effects of solar wind magnetosphere coupling in the context of the expanding contracting polar cap boundary model [PDF]

, 2006
This paper reviews the coupling between the solar wind, magnetosphere and ionosphere. The coupling between the solar wind and Earth’s magnetosphere is controlled by the orientation of the Interplanetary Magnetic Field (IMF).

Central polar cap convection response to short duration southward Interplanetary Magnetic Field [PDF]

Annales Geophysicae, 2000
Central polar cap convection changes associated with southward turnings of the Interplanetary Magnetic Field (IMF) are studied using a chain of Canadian Advanced Digital Ionosondes (CADI) in the northern polar cap.

On solar protons and polar cap absorption: Constraints on an empirical relationship [PDF]

, 2004
International audienceA large database of Solar Proton Events (SPE) from the period 1995 to 2001 is used to investigate the relationship between proton flux at geostationary orbit and Cosmic Noise Absorption (CNA) in the auroral zone. The effect of solar

Do the Throat Auroras Create Polar Cap Patches?

Geophysical Research Letters, 2023
Throat auroras and polar cap patches are common phenomena in the polar ionosphere resulting from magnetosphere‐ionosphere coupling. A campaign was organized, with all‐sky imagers at Yellow River Station, the European Incoherent Scatter Svalbard Radar ...

Representation of the auroral and polar ionosphere in the International Reference Ionosphere (IRI) [PDF]

Advances in Space Research, 2013
This issue of Advances in Space Research presents a selection of papers that document the progress in developing and improving the International Reference Ionosphere (IRI), a widely used standard for the parameters that describe the Earths ionosphere.

Coordinated Cluster, ground-based instrumentation and low-altitude satellite observations of transient poleward-moving events in the ionosphere and in the tail lobe [PDF]

, 2001
During the interval between 8:00–9:30 on 14 January 2001, the four Cluster spacecraft were moving from the central magnetospheric lobe, through the dusk sector mantle, on their way towards intersecting the magnetopause near 15:00 MLT and 15:00 UT ...

Seasonal variations and north–south asymmetries in polar wind outflow due to solar illumination [PDF]

Annales Geophysicae, 2016
The cold ions (energy less than several tens of electronvolts) flowing out from the polar ionosphere, called the polar wind, are an important source of plasma for the magnetosphere.

Effects of energetic electrons on the electrodynamics in the ionosphere [PDF]

, 2004
International audienceFrom the observations by the PIXIE and UVI cameras on board the Polar satellite, we derive global maps of the precipitating electron energy spectra from less than 1keV to 100keV.
