The scientific work proposed here will carry out the research and development necessary to create a new, unique set of high-latitude electro-dynamic, ionospheric-thermospheric-­‐magnetospheric cyberbased tools and products that will be available to the entire geosciences community. In combination, the data products from this project will allow the derivation of a first principle electromagnetic solution for the auroral ionosphere. Project will develop a new set of data resources for the geoscience community in the form of a complete electromagnetic solution of the auroral ionosphere and will focus on developing the ?Data Infrastructure for Communities? component of the EarthCube Integrative Activities. The project will thus allow access to not only the desired derived products, but also provide support for other modeling efforts by allowing access to the database of input data and intermediary products. The system will also be designed to be extensible, allowing additional data products and models to be integrated into the system. The system will fully support existing standards that are used in the broader geosciences community such as the Data Access Protocol (DAP).The research undertaken in this proposal will enable transformative research in two otherwise separated fields: magnetosphere-­‐ionosphere and neutral atmosphere. The MIAC project addresses the complete electromagnetic solution of the auroral ionosphere, through an implementation that matches the goals of the EarthCube program. The intent is to develop a series of interlocking web services that provide access to the underlying MIAC datasets (AMPERE, SuperDARN and SuperMAG), that apply the science algorithms to derive the desired electro-­ dynamic products, and provide data translation and visualization services. This mesh of services will be open to the community and will allow users to access any individual service. The research undertaken in this project will enable transformative research in two otherwise separated fields: magnetosphere-­‐ionosphere and neutral atmosphere through a) the high-­‐latitude electro-­‐dynamics couple to the incoming solar wind and magnetosphere along magnetic field lines; b) the changes in the ionosphere and thermosphere at high latitudes provide changes to the conductivities throughout the polar region, which then effect the dynamics in the magnetosphere; c) the electrodynamic energy and momentum inputs get deposited in the upper atmosphere and launch neutral winds that then couple to ion velocities and transport compositional changes to the mid and low latitudes; d) the winds and composition couple to waves impinging from the lower atmosphere.

这里提议的科学工作将进行必要的研究和开发，以创建一套新的、独特的高纬度电动、电离层-热层-磁层网络工具和产品，供整个地球科学界使用。综合起来，该项目的数据产品将能够推导出极光电离层的第一原理电磁解。该项目将以极光电离层完整电磁解的形式为地球科学界开发一套新的数据资源，并将重点开发？社区数据基础设施？EarthCube综合活动的组成部分。因此，该项目将不仅允许访问所需的衍生产品，而且通过允许访问输入数据和中间产品的数据库，为其他建模工作提供支持。该系统还将设计成可扩展的，允许将更多的数据产品和模型纳入该系统。该系统将充分支持更广泛的地球科学界使用的现有标准，如数据访问协议，本提案中进行的研究将使两个原本分离的领域的变革性研究成为可能：磁层-电离层和中性大气层。MIAC项目通过与EarthCube计划目标相匹配的实施，解决了极光电离层的完整电磁解决方案。其目的是开发一系列互锁网络服务，提供对底层MIAC数据集（AMPERE、SuperDARN和SuperMAG）的访问，应用科学算法来获得所需的电致动器动态产品，并提供数据翻译和可视化服务。这种服务网络将向社区开放，并允许用户访问任何个人服务。在该项目中进行的研究将使两个不同领域的变革性研究成为可能：磁层-&电离层和中性大气层，具体方法是：a）高纬度&电子电离层&;动态耦合到传入的太阳风和磁层沿着磁场线; B）高纬度电离层和热层的变化使整个极地区域的电导率发生变化，从而影响磁层的动态; c）、电动能量和动量输入在高层大气中沉积，并发射中性风，然后耦合到离子速度和传输成分的变化d）风和成分耦合到从低层大气撞击的波。
