Electron Thermal Flux and Temperature Maps Based on the Global Survey of Electron Precipitation Due To Whistler-Mode Waves

Electron thermal fluxes entering upper ionospheric altitudes define electron temperature distribution down to the F ionospheric layer. Electron heat/thermal fluxes are formed at magnetospheric altitudes by many different heating mechanisms via interactions of plasmaspheric cold background electrons with hot magnetospheric population and wave-particle interaction processes. However, the knowledge of electron precipitation distribution driven by the waves on the global scale is limited and requires additional experimental, data analysis, and theoretical studies. This paper uses a comprehensive global survey of electron precipitation and whistler waves by Ma et al. (2020, 2021, https://doi.org/10.1029/2020gl088798, https://doi.org/10.1029/2021ja029644) that based on Van Allen Probes observations from September 2012 to September 2019. The electron precipitation and whistler waves were used as an input to SuperThermal ElecTrons transport code to reveal the role of magnetosphere-ionosphere-atmosphere energy interplay the formation of electron heat fluxes entering upper ionospheric altitudes. The electron heat fluxes and temperature results that are presented in this manuscript cover the AE index ranges of AE < 100 nT, 100 < AE < 500 nT, and AE > 500 nT, as the function of geographical and magnetic latitudes and magnetic local time, and are only affiliated with whistler wave activities.
