This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The overall goal of this project is to increase understanding of the conjugate nature of the polar ionospheres, which in part helps understanding the multi-scale global solar wind, magnetosphere, and ionosphere system. The project utilizes numerous types of ionospheric remote sensing instrumentation, including: terrestrial GPS receivers, GPS satellite occultation receivers, all-sky imagers, riometers, and magnetometers currently deployed in the Arctic and Antarctic to estimate the 3-D time histories of the ionospheric electron density and also to estimate the polar wind in these polar regions. Furthermore, additional GPS instrumentation will be deployed in Antarctica to increase the number and improve the spatial distribution of GPS receivers in this region. Import aspects of this investigation are: (1) utilization of a large array of instrumentation in the Arctic and Antarctic regions to provide the maximum number of measurements of the ionosphere, (2) the modification and deployment of commercial-off-the-shelf GPS receivers in remote Antarctic locations to improve spatial distribution of GPS measurements, (3) development of a new estimation algorithm for estimating the polar wind, and (4) estimation of 3-D electron density time histories and conductances in conjugate polar ionospheres. The fieldwork and analysis efforts associated with this project are highly suitable for involvement and research training of graduate and undergraduate students.

该奖项是根据2009年《美国复苏与再投资法》（公法111-5）资助的。该项目的总体目标是提高对极性离子层的共轭性质的理解，这在一定程度上有助于理解多尺度的全球太阳风，磁层和电离层系统。该项目利用了多种类型的电离层遥感仪器，包括：陆地GPS接收器，GPS卫星固有螺型接收器，目前部署在北极和南极中的所有天空成像仪，整个成像仪和磁力仪，以估计这些极性电子密度和极性区域的3-D时间历史。此外，将在南极洲部署其他GPS仪器，以增加数量并改善该地区GPS接收器的空间分布。该调查的进口方面是：（1）利用北极和南极区域中的大量仪器，以提供电离层的最大测量值，（2）（2）在远程南极中的商业式GPS接收器的修改和部署，以改善GPS测量的空间分布，以改善GPS的空间分布（3）新的估算值（3）新的估算值（3）新的估算值，即新的（3）新的估算值，即新的（3）新的估算值的估算值（3）在共轭极性离子层中的3-D电子密度时间历史和电导的估计。与该项目相关的现场工作和分析工作非常适合研究生和本科生的参与和研究培训。
