太阳高能粒子（SEP）事件不仅对航天器造成严重的辐射危害，也对在太空旅行的人类造成严重的健康风险。事实上，SEP环境的精确建模是天体物理学和太阳系任务以及人类空间探索的优先要求。欧洲航天局的太阳高能粒子环境建模（sepm）应用服务器是一个万维网接口，包含1973年至2013年的一整套交叉校准数据，以及新的SEP工程模型和工具。统计和物理建模技术已经包括在内，为了覆盖环境不仅在1 AU，而且在0.2 AU至1.6 AU的内日球层，使用新开发的基于物理的激波和粒子模型来模拟逐渐SEP事件的粒子通量分布。利用sepm，可以研究SEP峰值通量和综合通量统计，以及SEP高通量周期的持续时间。此外，还包括影响工具，以便计算各种工程情景的单事件扰动率和辐射剂量。
Solar energetic particle (SEP) events are a serious radiation hazard for spacecraft as well as a severe health risk to humans traveling in space. Indeed, accurate modeling of the SEP environment constitutes a priority requirement for astrophysics and solar system missions and for human exploration in space. The European Space Agency's Solar Energetic Particle Environment Modelling (SEPEM) application server is a World Wide Web interface to a complete set of cross‐calibrated data ranging from 1973 to 2013 as well as new SEP engineering models and tools. Both statistical and physical modeling techniques have been included, in order to cover the environment not only at 1 AU but also in the inner heliosphere ranging from 0.2 AU to 1.6 AU using a newly developed physics‐based shock‐and‐particle model to simulate particle flux profiles of gradual SEP events. With SEPEM, SEP peak flux and integrated fluence statistics can be studied, as well as durations of high SEP flux periods. Furthermore, effects tools are also included to allow calculation of single event upset rate and radiation doses for a variety of engineering scenarios.
