Description
Local precipitation loss due to pitch angle scattering by magnetospheric waves is the focus of our analysis. Plasma waves can alter the course of a charged particle and influence a previously trapped electron from the magnetosphere to penetrate the Earth’s upper atmosphere. Once in the upper atmosphere, a charge particle can ionize air molecules leading to the destruction of ozone and interfere with technological systems. It is critical that particle measurements from different platforms are inter-calibrated and validated as LEO data can be a proxy for high latitude data for radiation belt models.
The proposed project aims to establish a predictable relationship between low-Earth-orbit and high altitude orbit data. We use coordinated electron measurements from the Van Allen Probes, or Radiation Belt Storm Probes (RBSP), and the Polar Operational Environmental Satellites (POES) to build a neural network. We reconstruct equatorial electron flux measurements using inputs from POES, geomagnetic indices, and L shell and MLT values.
