标题： Data-Driven Modelling of the Van Allen Belts: The 5DRBM Model for Trapped Electrons

摘要： 地球液态铁核的旋转维持着磁层，将带电粒子，主要是电子和质子，捕获到称为范艾伦辐射带的结构中。这些辐射带中带电高能粒子的密度可能对敏感仪器非常具有破坏性，在围绕地球运行的椭圆轨道上，卫星每次轨道都要穿越这些区域，如欧洲航天局的INTEGRAL和XMM-Newton任务所示。本文介绍了5DRBM-e模型的第一个工作版本，这是一个全球性的、数据驱动的捕获电子辐射带模型。该模型基于INTEGRAL和XMM-Newton卫星在其长时间椭圆轨道上分别16年和19年的运行期间，通过搭载的辐射监测器进行的原位电子测量。目前形式的该模型，涵盖了能量范围从0.7到1.75 MeV的捕获电子的积分通量。将5DRBM-e与众所周知的AE8min/max和AE9mean模型在低偏心率GPS轨道上的交叉验证显示出极好的一致性，并证明新模型可用于提供沿地球周围广泛不同轨道的可靠预测，以用于设计、规划和操作卫星，并具有更精确的仪器安全裕度。未来的工作将包括根据不同能量的电子和质子辐射测量数据扩展该模型。 显示英文摘要

摘要： The magnetosphere sustained by the rotation of the Earth's liquid iron core traps charged particles, mostly electrons and protons, into structures referred to as the Van Allen belts. These radiation belts, in which the density of charged energetic particles can be very destructive for sensitive instrumentation, have to be crossed on every orbit of satellites traveling in elliptical orbits around the Earth, as is the case for ESA's INTEGRAL and XMM-Newton missions. This paper presents the first working version of the 5DRBM-e model, a global, data-driven model of the radiation belts for trapped electrons. The model is based on in-situ measurements of electrons by the radiation monitors on board the INTEGRAL and XMM-Newton satellites along their long elliptical orbits for respectively 16 and 19 years of operations. This model, in its present form, features the integral flux for trapped electrons within energies ranging from 0.7 to 1.75 MeV. Cross-validation of the 5DRBM-e with the well-known AE8min/max and AE9mean models for a low eccentricity GPS orbit shows excellent agreement, and demonstrates that the new model can be used to provide reliable predictions along widely different orbits around Earth for the purpose of designing, planning, and operating satellites with more accurate instrument safety margins. Future work will include extending the model based on electrons of different energies and proton radiation measurement data.
