1. Substorm dependence of plasmaspheric hiss

   We analyze wave and particle data from the CRRES satellite to determine the variability of plasmaspheric hiss (0.1 < f < 2 kHz) with respect to substorm activity as measured […]

2. Modeling outer-zone relativistic electron response to whistler-mode chorus activity during substorms

   Understanding the behavior of relativistic electrons in the Earth’s outer radiation belt during substorms and storms is a current challenge in magnetospheric physics. In this paper, we model energetic electron […]

3. Diffuse auroral electron scattering by electron cyclotron harmonic and whistler mode waves during an isolated substorm

   There are two main theories for the origin of diffuse auroral electron precipitation: precipitation by electrostatic ECH waves and precipitation by whistler mode waves. Here we analyze a case event […]

4. Evidence for chorus-driven electron acceleration to relativistic energies from a survey of geomagnetically disturbed periods

   [1] We perform a survey of the plasma wave and particle data from the CRRES satellite during 26 geomagnetically disturbed periods to investigate the viability of a local stochastic electron […]

5. Evolution of energetic electron pitch angle distributions during storm time electron acceleration to megaelectronvolt energies

   We investigate the pitch angle distributions of 0.15-1.58 MeV electrons observed during the 9-15 October 1990 storm measured by the Combined Release and Radiation Effects Satellite (CRRES) spacecraft. This storm […]

6. Favored regions for chorus-driven electron acceleration to relativistic energies in the Earth’s outer radiation belt

   [1] Pitch angle and energy diffusion rates for scattering by whistler-mode chorus waves are proportional to the wave magnetic field intensity and are strongly dependent on the frequency distribution of […]

7. Statistical analysis of relativistic electron energies for cyclotron resonance with EMIC waves observed on CRRES

   Electromagnetic ion cyclotron (EMIC) waves which propagate at frequencies below the proton gyrofrequency can undergo cyclotron resonant interactions with relativistic electrons in the outer radiation belt and cause pitch-angle scattering […]

10. ‘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 […]
