Chorus waves induce both electron acceleration and loss. In this letter, we provide significantly improved models of electron lifetime due to interactions with chorus waves. The new models fill the gap that previous models have on some magnetic local time (MLT) sectors of the Earth's magnetosphere. This improvement is critical for modeling studies. The lifetime models developed using two different methods are valid for electrons with an energy range from 1 keV to 2 MeV. To facilitate the integration of these new models into different ring current and radiation belt codes, we parameterize the electron lifetime as a function of $L$-shell and electron kinetic energy at each MLT and geomagnetic activity (Kp). The parameterized electron lifetimes exhibit strong dependencies on $L$-shell, MLT, and energy. Simulations using these new models demonstrate improved agreement with satellite observations compared to simulations using previous models, advancing our understanding of electron dynamics in the magnetosphere.

由于高能电子与合唱波的相互作用而改进的寿命模型


合唱波会引起电子加速和损耗。在这封信中，我们提供了由于与合唱波相互作用而显着改进的电子寿命模型。新模型填补了以前模型在地球磁层的某些磁性本地时间 （MLT） 扇区上的空白。这种改进对于建模研究至关重要。使用两种不同方法开发的寿命模型适用于能量范围为 1 keV 至 2 MeV 的电子。为了便于将这些新模型集成到不同的环流和辐射带代码中，我们将电子寿命参数化为每个 MLT 和 $L$ 壳层和电子动能 （Kp） 的函数。参数化电子寿命对 $L$ 壳层、MLT 和能量表现出很强的依赖性。与使用以前模型的模拟相比，使用这些新模型的模拟表明与卫星观测的一致性更高，从而促进了我们对磁层中电子动力学的理解。
