U.S.-Turkey Collaborative Research: Very Low Frequency Remote Sensing of the Lower Ionosphere

0425902 InanDescription：该项目支持加州帕洛阿尔托斯坦福大学电气工程系Umran Inan博士与土耳其埃拉齐格Firat大学物理系Esat Guzel和Ali Yesil博士的合作项目。他们建议对美国和欧洲地区的电离层和辐射带的闪电引起的扰动进行定量比较。这笔资金将允许斯坦福大学的科学家和土耳其Firat大学的访问者在这些电离层遥感活动中进行合作。研究人员试图为定量比较美国和欧洲地区的电离层和辐射带的闪电扰动提供依据。到目前为止，关于这种现象的大多数数据都是在西半球获得的，科学信息的分量表明，高海拔和辐射带的闪电效应可能主导着全球范围内的其他过程。研究范围：该研究计划将促进在欧洲地区建立和进行甚低频观测，从而提供比较的基础，以促进全球推断和结论。根据这项合同，斯坦福大学的工作人员将与Firat大学合作，在土耳其的埃拉齐格市部署他们的一台甚低频接收器。在土耳其国家科学和技术研究委员会(TUBITAK)的支持下，Firat大学提供数据数字化和记录设备，以促进数据的持续获取。拟议方案的所有数据都将通过互联网进行分析，并计划进行一系列年度访问，以最大限度地扩大两个机构之间的互动和信息交流。

0425902 InanDescription: This project supports a cooperative project by the Dr. Umran Inan, Department of Electrical Engineering at Stanford University, Palo Alto, California and Drs. Esat Guzel and Ali Yesil, of the Physics Department, Firat University, Elazig, Turkey. They propose to develop a quantitative comparison of lightening-induced disturbances of the ionosphere and the radiation belts in the American and European sectors. The funds will allow for travel of Stanford scientists and visitors from FIRAT University in Turkey for collaborating in these ionospheric remote sensing activities. The investigators seek to provide a basis for quantitative comparison of lightning-induced disturbances of the ionosphere and the radiation belts in the American and European sectors. Most of the current data on such phenomena has so far been obtained in the western hemisphere, and the weight of scientific information indicates that lightning-induced effects at high altitudes and in the radiation belts may dominate other processes on a global scale. Scope: The research program will facilitate the establishment and conduct of VLF observations in the European sector, thus providing a basis for comparison to facilitate global extrapolations and conclusions. Under this award, Stanford University staff will partner with FIRAT University, deploying one of their VLF receivers in the city of Elazig in Turkey. With support from NSF's counterpart in Turkey (Scientific and Technical research Council of Turkey, TUBITAK) FIRAT University provides the data digitization and recording equipment to facilitate continuous acquisition of the data. All data from the proposed program will be available for analysis over the Internet, and a series of annual visits are planned to maximize interactions and information exchange between the two institutions.
