ATM-0000171SchunkThe proposed research is a continuation of theoretical studies of the effects that plasma and neutral gas transport processes have on the Earth's ionosphere and thermosphere. The research spans a 5-year period and will be conducted by a group that is composed of six scientists and a graduate student. The research involves model/data comparisons, theoretical studies of ionosphere dynamics and electrodynamics, polar wind studies, and high-resolution thermosphere studies. The overall approach is to consider the ionosphere as an integrated system, which interacts with both the magnetosphere and thermosphere. The members of the group will study different, but related, ionospheric problems, with the result that almost all of the major ionospheric regions will be studied, including the E region, F region, and topside ionosphere at equatorial, middle, and high latitudes. In the course of these studies, some of the group's models will be upgraded or improved, but most of the proposed studies will be conducted with existing ionospheric, thermospheric, electrodynamic, and polar wind models. Also, in many of the proposed studies, data will be needed from several incoherent scatter radars, ionosondes, ground-based magnetometers, superDARN radars, and satellites, but all of the data required are either already available or will be available on the World Wide Web in the near future. The proposed research is directly relevant to the National Space Weather Program as well as to the NSF-sponsored community-wide initiatives called CEDAR and GEM, and to NASA's TIMED satellite.

ATM-0000171SCHUNK拟议的研究是对等离子体和中性气体传输过程对地球电离层和热圈的影响的理论研究的延续。 该研究跨越了5年，将由由六名科学家和一名研究生组成的小组进行。 该研究涉及模型/数据比较，电离层动力学和电动力学的理论研究，极性风研究和高分辨率热层研究。 总体方法是将电离层视为一种集成系统，该系统与磁层和热圈相互作用。 该小组的成员将研究不同但相关的电离层问题，结果将研究几乎所有主要的电离层区域，包括赤道，中和高纬度的E区域，F区域和顶部电离层。 在这些研究的过程中，该小组的某些模型将得到升级或改进，但是大多数建议的研究将使用现有的电离层，热层，电动力学和极性风模型进行。 同样，在许多拟议的研究中，将需要从几个不一致的散射雷达，Ionosondes，地面磁力计，超档雷达和卫星中获得数据，但是所需的所有数据都已经可用，或者在不久的将来都可以在万维网上提供。 拟议的研究与国家太空天气计划以及NSF赞助的社区范围内的计划直接相关，称为Cedar和Gem，以及NASA的定时卫星。
