[PEM13-04] Electromagnetic disturbance and wave-particle coupling event research based on CSES
Keywords:CSES satellite, electromagnetic waves, wave particle interaction events in extremely low L-shells, typical space weather events
China's Zhangheng-1 satellite (also called CSES) is equipped with an electric field instrument, magnetometer, high-energy particle detector, and plasma instrument, which can perform good observation and research on space electromagnetic environment and space weather events. Based on more than five years of data from the CSES satellite, we have conducted detailed and in-depth observations and studies on the excitation and propagation of various electromagnetic waves in the space environment, particle dynamics processes and wave particle interactions in radiation belts, plasma disturbances, and other events; We have monitored, tracked, and analyzed space events such as magnetic storms, solar flares, solar proton events, and super gamma storms.
Based on the CSES, the excitation and propagation of various electromagnetic waves in the space environment we observe mainly include quasi-periodic whistler waves, ionospheric hissing waves, proton whistler waves, lightning whistler waves, magnetospheric line resonance waves, and various artificial ground electromagnetic signals. We have conducted extensive in-depth research and reports on the excitation and propagation of these waves.
The high-energy particle detector carried by the CSES can observe high-energy electrons and protons in the Earth's radiation belt and the South Atlantic anomaly area with higher detection efficiency. It has high energy resolution, good particle identification efficiency, and high pitch angle resolution. The satellite is also equipped with X-ray monitors, so it can also observe X-rays during flares and the solar proton events. This provides a great opportunity for studying natural disaster events and wave particle interaction at extremely low L-shell region in ionosphere. We conducted observation based on the CSES and numerical simulation of wave particle interaction events induced by whistler waves, hiss waves and magnetosonic waves, to deeply analyze the particle acceleration and diffusion effect. We still study the high-energy proton loss effect at the outer boundary of the inner radiation band due to the bending and scattering of magnetic field lines during magnetic storms and some typical space weather events such as solar flare X-rays and solar proton events.
