U.S.-China Cooperative Research: Solar Seismological and Long-Term Variability Studies

研究目标是获得和分析在Sclera(亚利桑那大学圣卡塔利纳大学天文相对论实验实验室)和昆明附近的云南天文台(中国)所做的太阳振荡和长期太阳变率观测。组织这项国际合作是为了提供覆盖一天中相当大一部分时间的太阳观测，从而大大减少单一地点的数据中存在的虚假日间信号的其他严重影响。观测将使用目前在亚利桑那大学和云南天文台运行的巩膜太阳地震仪进行。这套设施通过一个成本相对较低的地面计划，为美国和中国的科学家提供了处于太阳物理学前沿的研究和教育机会。国际合作的第一批成果预计将改善有关太阳内部区域结构和太阳长期可变性的信息，这可能会对地球气候的长期变化产生影响。

The research objectives are to obtain and analyze observations of solar oscillations and long-term solar variability taken at SCLERA (The University of Arizona Santa Catalina Laboratory for Experimental Relativity by Astrometry) and at Yunnan Observatory near Kunming, China. The international collaboration has been organized in order to furnish observations of the Sun covering a sizeable fraction of a day and, consequently, to significantly reduce the otherwise serious effects of false diurnal signals present in the data of a single site. The observations will be obtained with the SCLERA solar seismographs currently in operation at the University of Arizona and at Yunnan Observatory. The set of facilities offers research and educational opportunities that are at the forefront of solar physics for both U.S. and Chinese scientists through a relatively low-cost ground-based program. The first results from the international cooperation are expected to yield improved information about the structure of the interior regions of the Sun and about long-term solar variability, which may have an impact on long-term variations in the Earth's climate.
