项目摘要

The influence of precipitating energetic particles on the composition and dynamics of the atmosphere is a challenging issue in climate modeling. Such particles can also be used as test stimulus for inter-comparison of the chemistry part in different models and comparison of model results to observations – which will be done with the data derived from this model within the framework of HEPPA and the MIPAS data user community. This proposal is concerned with the refinement and validation of the Atmospheric Ionization Module Osnabrück (AIMOS), giving the 3D precipitation pattern of solar and magnetospheric particles, and its implementation as a data server to the atmospheric modeler community, in particular the groups participating in CAWSES. Question to be addressed include: (a) validation of the spatial precipitation pattern inferred from the satellite data, (b) extension of the data base (satellite measurements), (c) development/implementation of a proxy for 3D magnetospheric particle precipitation from the kp index, (d) analysis of particle precipitation in the South Atlantic Anomaly, and (e) determination of 3D ionization maps in extreme events such as Carrington’s white light flare. More technical questions include (f) the assurance of data quality (sensor degeneration, crosstalk, magnetopause inside satellite orbit), (g) the development of an interpolation routine to adopt to the spatial grids of the different model atmospheres, and (h) the development and implementation of a user interface for easy access.

降水高能粒子对大气成分和动力学的影响是气候模拟中的一个具有挑战性的问题。这些颗粒也可以用作测试刺激物，用于不同模型中化学部分的相互比较以及模型结果与观察结果的比较-这将在HEPPA和MIPAS数据用户社区的框架内使用来自该模型的数据进行。这项建议涉及改进和验证大气电离模块Osnabrück（AIMOS），提供太阳和磁层粒子的三维降水模式，并将其作为数据服务器提供给大气建模界，特别是参加CAWSES的各小组。要解决的问题包括：（a）验证从卫星数据推断的空间降水模式，（B）扩展数据库（卫星测量），（c）根据kp指数开发/实施三维磁层粒子降水代用指标，（d）分析南大西洋异常区的粒子降水，以及（e）确定卡林顿白色光耀斑等极端事件中的3D电离图。技术性较强的问题包括：（f）保证数据质量（传感器退化、串扰、卫星轨道内的磁层顶）;（g）开发插值程序，以适应不同大气模型的空间网格;（h）开发和实施用户界面，以便于使用。
