Characterization of the radiation environment in Earth's magnetosphere and its impact on the atmospheric phenomena
Session ID#: 82313
Session Description:
Radiation hazards due to energetic particles in geospace have a significant effect on human technology at altitudes above the troposphere. Exposure to energetic particles often leads to malfunctions and unexpected failures of electronics onboard spacecraft. Ionizing radiation also has a global impact on the Earth's upper atmosphere by producing scintillations which affect navigation systems and triggering electrochemical reactions which can destroy atmospheric ozone.
Particle populations significant in the context of the radiation hazard includes galactic cosmic rays (GCR), anomalous galactic cosmic rays (ACR), solar energetic particles (SEPs), and electrons and protons of the inner and outer radiation belts.
This session seeks contributions focused on transport and acceleration of SEP as they move towards the Earth, dynamics of SEPs and GCRs in the Earth’s magnetosphere and their effect on the inner radiation belt, and dynamics of the outer radiation belt electrons, and their impact on the ionospheric and atmospheric phenomena.
