2. Plasmasphere dynamics in the duskside bulge region: a new look at an old topic

   Data 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 […]

3. Survey of upper band chorus and ECH waves: implications for the diffuse aurora

   The 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 […]

4. Substorm dependence of chorus amplitudes: Implications for the acceleration of electrons to relativistic energies

   Intense 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 […]

6. 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 […]

7. Additional stratospheric NOx production by relativistic electron precipitation during the 2004 spring NOx descent event

   We 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 […]

8. Atmospheric impact of the Carrington event solar protons

   The 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 […]

9. Energetic electron precipitation during substorm injection events: high-latitude fluxes and an unexpected midlatitude signature

   Geosynchronous Los Alamos National Laboratory (LANL-97A) satellite particle data, riometer data, and radio wave data recorded at high geomagnetic latitudes in the region south of Australia and New Zealand are […]

10. Observations of relativistic electron precipitation from the radiation belts driven by EMIC waves

    For 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 […]

11. Radiation belt electron precipitation by man-made VLF transmissions

    Enhancements of drift-loss cone fluxes in the inner radiation belt have been observed to coincide with the geographic location of the powerful VLF transmitter NWC. In this paper we expand […]

12. Significance of transient luminous events to neutral chemistry: experimental measurements

    For many years it has been suggested that transient luminous events (TLE) occurring over thunderstorms may produce significant modifications to neutral atmospheric chemistry. Some have speculated that large ionisation increases […]
