The project will examine the structure and dynamics of the polar thermosphere and its linkages with the active phase of the Solar Cycle in 2000-2002. The research includes optical observations of polar auroral arcs from circumarctic sites across the polar cap. In addition to data gathering at ground stations in Alaska, Denmark, Canada, Norway and other sites, satellite information will be used to study solar storms in the polar ionosphere and thermosphere. A wide variety of instruments will be used to measure the intensity and variability of solar energy entering Earth's atmosphere during a period of intense solar storms for the next several years. The results of this project will be important to understanding the role of solar storms in disrupting satellite and radio communications.

该项目将审查极地热层的结构和动力学及其与2000-2002年太阳周期活跃期的联系。这项研究包括从北极圈穿过极冠的地点对极地极光弧进行光学观测。除了在阿拉斯加、丹麦、加拿大、挪威和其他地点的地面站收集数据外，卫星信息还将用于研究极地电离层和热层中的太阳风暴。在未来几年的强烈太阳风暴期间，将使用各种各样的仪器来测量进入地球大气层的太阳能的强度和变化性。该项目的结果对于理解太阳风暴在扰乱卫星和无线电通信方面的作用将是重要的。
