Dataset for "Electron Thermal Flux and Temperature Maps Based on the Global Survey of Electron Precipitation due to Whistler-mode Waves"

This is the dataset for paper "Electron Thermal Flux and Temperature Maps Based on the Global Survey of Electron Precipitation due to Whistler-mode Waves", submitted to Journal of Geophysical Research: Space Physics.<br>Electron thermal fluxes entering upper ionospheric altitudes define electron temperature distribution down to F ionospheric layer. Electron heat/ thermal fluxes are forming 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) 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 (STET) transport code to reveal the role of magnetosphere-ionosphere-atmosphere (MIA) 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 &lt; 100 nT, 100 &lt; AE &lt; 500 nT, and AE &gt; 500 nT, as the function of geographical and magnetic latitudes and magnetic local time, and are only affiliated with whistler wave activities.

本数据集对应投稿于《地球物理学研究杂志：空间物理学》的论文《基于哨声模波（whistler-mode waves）诱发电子沉降全球普查的电子热通量与温度分布图》。抵达电离层上层高度的电子热通量，决定了直至F电离层的电子温度分布。电子热（量）通量于磁层高度生成，其形成途径涵盖多种加热机制：包括等离子层冷背景电子与热磁层粒子群体的相互作用，以及波粒相互作用过程等。然而，当前学界对全球尺度下波驱动电子沉降分布的认知仍存在不足，亟需补充更多实验、数据分析与理论研究工作。本文采用Ma等人（2020、2021）基于2012年9月至2019年9月范艾伦探测器（Van Allen Probes）观测数据完成的电子沉降与哨声波全球普查数据集。研究将电子沉降与哨声波数据作为输入，送入超热电子（SuperThermal ElecTrons, STET）传输代码，以揭示磁层-电离层-大气（MIA）能量相互作用在电离层上层电子热通量形成过程中所发挥的作用。本文展示的电子热通量与温度结果，涵盖AE指数（AE index）<100 nT、100<AE<500 nT以及AE>500 nT三个区间，以地理纬度、磁纬度与磁地方时为自变量，且仅对应哨声波活动。
