项目摘要

Research has been made for the purpose of investigating the recent research trend in earth science, and performing a firm grasp of the present status and the proposal to the future. In FY 1998, a symposium was planned and held in order to survey the development of earth science in varieties of field as a milestone for the centennial of geodesy. Here, the seven issues, viz., the overview on the history of earth science, the radar aeronomy which has made a remarkable progress in the solar terrestrial physic, the development of the climatic system science referring to the elucidation of EL Nino study in theatmospheric and ocean science fields, the present status of earthquake prediction in the field of seismology, the dynamics of magma and the prediction of volcanic eruption in the field of volcanology, the big achievements which the space probes have performed in the planetary science field, and advanced space technology applications in the geodesy field, were summarized in view of the development and future prospect of earth sciences by the distinguished researchers in each field.These were published as a symposium report entitled "The new torrent in the view of the earth". In FY 1999, the symposium proceedings were distributed, and discussions among interested researchers were continued. It was evident in the above report that the GPS which is a global positioning system using the artificial satellite tends to possess a broad range of applications in the earth science fields. Hence, investigation was performed concerning GPS applications in close collaboration with the International symposium on GPS- Application to Earth Sciences and Interaction with other Space Geodetic Techniques. Moreover, survey on the international research trend in the planetary radio science at the international URSI meeting in Canada and arrangement for publishing the proposal on the future planetary exploration plan were performed.

研究的目的是调查地球科学的最新研究趋势，并对现状和未来提出建议。1998财政年度计划并举行了一次专题讨论会，以审查地球科学在各个领域的发展，作为大地测量学百年纪念的一个里程碑。在这里，七个问题，即，地球科学的发展史概述，在日地观测中取得显著进展的雷达高层大气学，大气科学和海洋科学领域中以厄尔尼诺现象为例的气候系统科学的发展，地震学领域中地震预报的现状，火山学领域中岩浆动力学和火山喷发预报，从地球科学的发展和未来前景的角度，总结了空间探测器在行星科学领域取得的重大成就，以及空间技术在大地测量领域的先进应用，并发表了题为“从地球看新潮流”的研讨会报告。1999财政年度，分发了专题讨论会的记录，并继续在感兴趣的研究人员之间进行讨论。从上述报告中可以明显看出，GPS是一种利用人造卫星的全球定位系统，它在地球科学领域有着广泛的应用。因此，与"全球定位系统-地球科学应用和与其他空间大地测量技术的相互作用“国际专题讨论会密切合作，对全球定位系统的应用进行了调查。此外，在加拿大召开的国际URSI会议上对行星射电科学的国际研究趋势进行了调查，并安排发表了未来行星探测计划的建议。
