‘Pancake’ electron distributions in the outer radiation belts
Electron pitch angle distributions sharply peaked at 90 degrees pitch angle were first recorded in the energy range 50 eV < E < 500 eV by the GEOS1 and GEOS2 […]

Plasmasphere dynamics in the duskside bulge region: a new look at an old topic
Read more of: Plasmasphere dynamics in the duskside bulge region: a new look at an old topicData acquired during several multiday periods in 1982 at ground stations Siple, Halley, and Kerguelen and on satellites DE 1, ISEE 1, and GEOS 2 have been used to investigate […]

Survey of upper band chorus and ECH waves: implications for the diffuse aurora
Read more of: Survey of upper band chorus and ECH waves: implications for the diffuse auroraThe origin of the diffuse aurora has been a source of controversy for many years. More recently, the question has taken a new significance in view of the associated changes […]

Substorm dependence of chorus amplitudes: Implications for the acceleration of electrons to relativistic energies
Read more of: Substorm dependence of chorus amplitudes: Implications for the acceleration of electrons to relativistic energiesIntense interest currently exists in determining the roles played by various wave-particle interactions in the acceleration of electrons to relativistic energies during/following geomagnetic storms. Here we present a survey of […]

Model of the energization of outer-zone electrons by whistler-mode chorus during the October 9, 1990 geomagnetic storm
Read more of: Model of the energization of outer-zone electrons by whistler-mode chorus during the October 9, 1990 geomagnetic storm[1] Relativistic (> 1 MeV) ‘killer electrons’ are frequently generated in the Earth’s inner magnetosphere during the recovery phase of a typical magnetic storm. We test the hypothesis that the […]

Additional stratospheric NOx production by relativistic electron precipitation during the 2004 spring NOx descent event
Read more of: Additional stratospheric NOx production by relativistic electron precipitation during the 2004 spring NOx descent eventWe analyze in detail the February 2004 Global Ozone Monitoring by Occultation of Stars (GOMOS) NO2 observations in the northern polar latitudes during the springtime descent of NOx from the […]

Atmospheric impact of the Carrington event solar protons
Read more of: Atmospheric impact of the Carrington event solar protonsThe Carrington event of August/September 1859 was the most significant solar proton event (SPE) of the last 450 years, about four times larger than the solar proton fluence of the […]

Observations of relativistic electron precipitation from the radiation belts driven by EMIC waves
Read more of: Observations of relativistic electron precipitation from the radiation belts driven by EMIC wavesFor some time theoretical modeling has shown that electromagnetic ion cyclotron (EMIC) waves should play an important role in the loss of relativistic electrons from the radiation belts, through precipitation […]
