项目摘要

EISCAT radars such as KST UHF radar, VHF radar and Svalbard EISCAT radar (ESR) are one of the greatest tools in the world for observing ionospheric phenomena in the auroral, polar cusp and cap regions. EISCAT radar systems provide us with essential physical parameters over the polar ionosphere. Solar-Terrestrial Environment Laboratory (STEL) has been playing a central role in promoting a variety of research projects using the ESR and KST radars of the EISCAT Scientific Association ; Japan, represented by NIPR, joined the EISCAT Scientific Association as the seventh associate country in April 1996. STEL, in collaboration with researchers across the nation, has been conducting Special Program (SP) experiments and creating Common Program (CP) data archives. The EISCAT database is available to collaborative researchers through network.Japanese Special Program (SP) experiments have been conducted in response to proposals submitted from collaborative researchers across the nation. Those proposals were evaluated by the Polar Radar Committee in STEL. In fiscal year 2003 five major SP projects were conducted: (1) research on black aurora; (2) research on ion upflows; (3) research on coupling process between the magnetosphere and ionosphere; (4) research on the lower thermosphere neutral wind ; and (5) research on Jovian inner magnetosphere with the spectrum observation of the synchrotron radiation. All of these projects except (5) were conducted on an international basis.One of the prominent scientific results in this fiscal year based on SP is a study of the lower thermosphere wind dynamics using both KST UHF and ESR radars. We conducted an 8-day run with the both radar systems which provide us with great oppotunities to study 2 atmospheric tidal waves as well as wind system at high latitudes. We also archived EISCAT Common Program data. Based on the CP database, various studies have been carried on.

KST超高频雷达、甚高频雷达和斯瓦尔巴德EISCAT雷达（ESR）等EISCAT雷达是世界上观测极光、极尖和极帽地区电离层现象的最佳工具之一。EISCAT雷达系统为我们提供极地电离层的基本物理参数。日地环境实验室（STEL）一直在利用ESR和KST雷达推动各种研究项目方面发挥核心作用；1996年4月，日本以NIPR为代表加入了EISCAT科学协会，成为第七个协约国。STEL与全国各地的研究人员合作，一直在进行特殊计划（SP）实验，并创建共同计划（CP）数据档案。EISCAT数据库可通过网络提供给合作研究人员。日本特别计划（SP）实验是根据全国合作研究人员提交的建议进行的。极地雷达委员会对这些建议进行了评估。在2003财政年度进行了五个主要的SP项目：(1)研究黑极光；(2)离子上流研究；(3)磁层与电离层耦合过程研究；(4)低层热层中性风研究；(5)利用同步辐射光谱观测研究木星内磁层。除(5)外，所有这些项目都是在国际基础上进行的。本财政年度基于SP的突出科学成果之一是使用KST UHF和ESR雷达对低层热层风动力学进行了研究。我们利用这两个雷达系统进行了为期8天的运行，为我们提供了研究高纬度地区大气潮汐波和风系统的绝佳机会。我们还存档了EISCAT公共程序数据。在CP数据库的基础上，进行了各种研究。
