CEDAR/GISMOS Substorm Studies

太阳风与受地球磁场限制的电离气体的相互作用导致磁场和气体(磁层)向下延伸到许多地球半径，并产生数百万安培的电流流经高纬度电离层，产生令人惊叹的被称为极光的光发射。该奖项是为了表彰一项名为GISMOS的合作观测和分析方案的继续，该方案利用雷达以及光学和磁场测量设备来确定与电流和极光发射相关的电场模式，其中已经成功地开展了几次活动。其目的是促进我们对先前通过太阳风-磁层相互作用在磁层中积累的能量突然释放所涉及的物理过程的理解，其中一部分沉积在电离层中，被称为磁亚风暴。

The interaction of the solar wind with ionized gas confined by the earth's magnetic field results in a long extension downwind to many earth radii of the magnetic field and gas (the magnetosphere) and the generation of currents of millions of amperes which flow through the high latitude ionosphere, and create the striking displays of light emission known as the aurora. This award is for the continuation of a cooperative observation and analysis program called GISMOS, of which several successful campaigns have taken place, using radar and optical and magnetic field measuring equipment to determine the pattern of electric field associated with the currents and auroral emissions. The objective is to advance our understanding of the physical processes involved in the sudden release of energy previously accumulated in the magnetosphere by the solar wind- magnetosphere interaction, part of which is deposited in the ionosphere and is known as a magnetic substorm.
