We propose to conduct an observationally-oriented study to investigate new discoveries concerning the dynamic processes that govern relativistic electrons and energetic ions in the near-Earth space environment. A fundamental question that remains unanswered is how charged particles are distributed along the magnetic field lines from one hemisphere to the other. In particular, the distribution near the atmospheric \u201closs cone\u201d is quite different from the distribution of particles that magnetically mirror further up the field. Understanding the relationship between those two parts of the distribution will provide new tools for both physical understanding and predictive modeling. This broad knowledge has great value for practical space weather applications, with important implications for the manmade technologies that operate in this region. <\/p>\n\n\n\n

Specifically, we propose to use the ISSI Bern forum as an international research center, where our team will seek to reach a global description of the particle distribution along the entire geomagnetic field line by using and combining datasets from three main missions observing the radiation belts: ESA\u2019s Proba V mission (EU), NASA\u2019s Van Allen Probes mission (USA), and JAXA\u2019s Arase (ERG) mission (Japan). Each mission brings a different latitudinal view of the belts, yet together will deliver a full description along the field line, and result in a new understanding of the dynamics. Through observations combined with numerical modeling, we will test various physical mechanisms that have been proposed to explain how plasmas and energetic particles are injected into and transported through the belts. Connecting the particle distribution with the magnetospheric electromagnetic waves that drive the dynamics will be at the deep center of the studies. We will also focus on the processes that affect precipitations of energetic particles in the Earth\u2019s upper atmosphere. <\/p>\n\n\n\n

Our international team is composed of 12 outstanding researchers hailing from top institutes in Europe, North America, and Asia, with each bringing access and expertise of at least one of the satellite datasets of the 3 missions. They share an expertise on observations and\/or theory\/modeling\/computation of particles and waves in Earth\u2019s inner magnetosphere. Working daily, collaboratively at ISSI, with each other\u2019s data will lead our team to an improved representation of the near-Earth radiation environment, delivering unprecedented and impactful research studies, based on a synthesis of vast satellite data coverage and state-of-the-art numerical simulations.<\/p>\n\n\n\n
