U.S.-Argentina Cooperative Program for Investigation of Traveling Ionospheric Disturbances

该奖项支持阿拉斯加大学地球物理研究所的Robert Hunsucker和阿根廷布宜诺斯艾利斯国家无线电传播计划（PRONARP）的S.M. Radicella在电离层扰动方面的合作研究。他们将研究在南北极光区产生的电离层扰动的传播，这些扰动向赤道传播了很长一段距离。两台电离层探空仪将捐赠给阿根廷，并由美国国家科学基金会在格陵兰岛、马萨诸塞州、波多黎各和秘鲁支持的非相干散射雷达链建立起来，以加强对干扰传播的监测。这些数据将有助于我们理解源自极光椭圆附近的高能电离层事件与由此产生的向赤道传播的扰动之间的关系。美国PI为合作带来了大气重力波和传播电离层扰动方面的大量专业知识。PRONARP的阿根廷人员熟悉这些设备，并将为今后的研究获得有用的数据。进一步的好处将来自南美洲电离层无线电仪器链的增强，这将为其他研究人员提供各种电离层研究。

This award supports cooperative research on ionospheric disturbances between Robert Hunsucker of the University of Alaska Geophysical Institute and S.M. Radicella, of the Programa Nacional de Radiopropagacion (PRONARP) in Buenos Aires, Argentina. They will study the propagation of travelling ionospheric disturbances, generated in the northern and southern auroral regions, which travel for long distances toward the equator. Two ionosondes will be donated to Argentina and set up to increase the monitoring of disturbance propagation by the NSF-supported chain of incoherent scatter radars in Greenland, Massachusetts, Puerto Rico and Peru. The data will help our understanding of the relationship between energetic ionospheric events originating near the auroral ovals and the resulting disturbances propagating toward the equator. The U.S. PI brings to the collaboration considerable expertise in atmospheric gravity waves and travelling ionospheric disturbances. The Argentine personnel at PRONARP are familiar with the equipment and will acquire useful data for future research. A further benefit will derive from the enhanced ionospheric radio instrumentation chain in South America which will be available to other investigators for a variety of ionospheric studies.
