0611717 LyonsAbstractThis is a two-year award to continue efforts to document and understand the causes of different types of auroral disturbances. The project relates to the ultimate goal of establishing the relationships between changes in the solar wind and interplanetary magnetic field, changes in the reconnection related ionospheric flows on the dayside, and the resulting types of auroral disturbances. Understanding these relationships is essential to improve specification and forecasting of the auroral disturbances, which can cause disruption of radio transmission and satellite communications, including the Global Positioning System. The main objective of the project is to derive and verify observational techniques based on recent investments in polar observation technology to identify the various auroral disturbances. Specific focus is on the determination of the nightside electric field reversal in the Harang discontinuity. The research work will be carried out mainly by graduate students.

0611717里昂摘要这是一个为期两年的奖项，继续努力记录和了解不同类型的极光扰动的原因。 该项目的最终目标是确定太阳风和行星际磁场的变化、与日侧电离层流动有关的重联变化以及由此产生的极光扰动类型之间的关系。 了解这些关系对于改进极光扰动的规格说明和预报至关重要，极光扰动可能造成无线电传输和卫星通信中断，包括全球定位系统中断。该项目的主要目标是根据最近对极地观测技术的投资，推导和验证观测技术，以确定各种极光扰动。具体的重点是在哈朗不连续的夜侧电场反转的测定。 研究工作将主要由研究生进行。
