Scientific paper

Recent studies have made the critical role of waves in controlling the dynamics of the Earth's radiation belts being more widely recognized. Chorus waves, for example, are now considered the most likely candidate of energizing relativistic (~MeV) electrons. However, determinative and systematic observational evidence is still needed for demonstrating and quantifying the dominant role of chorus waves. This is partially due to the scarce of in-situ wave measurements in both the temporal and spatial domain. Here we study the relationship between the precipitation of low-energy (~10keV) electrons, the intensification of chorus waves, and the acceleration of energetic (~MeV) electrons in the belt region. This study involves detailed and statistical comparisons of in-situ wave and electron observations from satellites in both low-Earth-orbits (LEOs), such as POES and DEMETER, and high-altitude orbits, such as CRRES and THEMIS. The goal of this study is to develop a new method of remote-sensing chorus waves from the LEO electron observations, based upon the theoretic prediction that injected low-energy electrons with anisotropic distributions give energy to the chorus wave and then precipitate into the atmosphere. Given the easy accessibility of the LEO and the low cost of LEO missions, this work is practically meaningful since the new remote-sensing method will not only help to make the most use of the accumulated decade-long LEO observations, but also can guide planning future space-weather monitoring missions.
