A novel technique to construct the global distribution of whistler mode chorus wave intensity using low‐altitude POES electron data

摘要: Although magnetospheric chorus plays a significant role in the acceleration and loss of radiation belt electrons, its global evolution during any specific time period cannot be directly obtained by spacecraft measurements. Using low-altitude NOAA Polar-orbiting Operational Environmental Satellite (POES) electron data, we develop novel physics-based methodology to infer wave intensity construct distribution with resolution less than an hour. We describe detail how apply technique satellite data performing two representative analyses, i.e., (i) for one point visualize estimation procedure (ii) particular validate method illustrative model. demonstrate that spatiotemporal equatorial magnetosphere can reasonably estimated from flux measurements made multiple POES satellites broad coverage L shell magnetic local time. Such data-based, dynamic model waves provide near-real-time information on scale where are available. A combination acquired using this direct spaceborne used evaluate quantitative scattering caused resonant wave-particle interactions thus variability.
