Abstract Based on one-hour average data observed by the MIMI/LEMMS instrument onboard the Cassini spacecraft from 2004 to 2017, we present an empirical model of energetic electrons (27 keV to 1937 keV) in Saturn’s magnetosphere. This model distinguishes between two different regions. In the inner magnetosphere ( 20RS), this model is constructed based on magnetodisk coordinates and represents the sheet-like structure at magnetotail. Gaussian distribution is used to fit the data along with the perpendicular distance to the warped magnetodisk. We also include a magnetopause model to filter the flux data. Finally, the results from this model are compared with those from SATRAD (SATurn RADiation model). Our new model based on Cassini data provides a picture of the energetic electron environment from 2.5 RS to 40 RS in Saturn’s magnetosphere.

基于卡西尼号数据的土星磁层高能电子经验模型

摘要 基于卡西尼号飞船上的 MIMI/LEMMS 仪器在 2004 年至 2017 年期间观测到的一小时平均数据，我们提出了土星磁层中高能电子（27 keV 至 1937 keV）的经验模型。该模型区分了两个不同的区域。在内磁层（20RS）中，该模型是基于磁盘坐标构建的，表示磁尾处的片状结构。高斯分布用于拟合数据以及与翘曲磁盘的垂直距离。我们还包括一个磁层顶模型来过滤通量数据。最后，将该模型的结果与 SATRAD（SATurn RADiation 模型）的结果进行比较。我们基于卡西尼号数据的新模型提供了土星磁层中从 2.5 RS 到 40 RS 的高能电子环境的图片。
