Description: This grant provides support for a joint research by a U.S. team headed by Dr. John W. Leibacher of the National Solar Observatory (NSO) in Tucson, AZ, and an Indian team headed by Dr. A. Bhatnagar, Director of the Udaipur Solar Observatory (USO) in Udaipur, India. The research, in its first phase, will cover site evaluation of Udaipur as one of six sites for the Global Oscillation Network Group (GONG) project. The GONG project seeks to obtain information through observations, made at different sites on the surface of the earth, of the oscillations at the surface of the sun, the earth's nearest star. Helioseismology, the study of these solar oscillations, has been developed as a new powerful tool that can probe the solar interior with considerable precision much in the same way that terrestial seismology reveals information about the interior of the earth. Because the instruments and the program of observation to be used during the second phase are quite sensitive and complicated, it is important to run certain evaluative experiments on the various sites under consideration around the globe, including the Udaipur site, before making the final selection of the six sites. Scope: Indian scientists have contributed significantly to the field of solar physics. The USO has a unique geographical location being in an area of considerable atmospheric clarity and at approximately opposite position around the globe to the NSO in Tucson. The support of the Government of India (GOI) will be crucial for the success of the experiments. This grant will enable the U.S. team to conduct the necessary preliminary tests and to negotiate with the GOI the required facilities from different governmental agencies.

描述：这笔赠款为亚利桑那州图森市国家太阳天文台(NSO)的John W.Leibacher博士领导的美国团队和印度乌代布尔Udaipur太阳天文台(USO)主任A.Bhatnagar博士领导的印度团队的联合研究提供支持。在第一阶段，这项研究将包括乌代布尔作为全球振荡网络组织(GONG)项目六个地点之一的地点评估。GONG项目寻求通过在地球表面不同地点进行的观测来获取有关太阳表面振荡的信息，太阳是地球上距离最近的恒星。研究这些太阳振荡的日震学已经发展成为一种新的强大工具，可以相当精确地探测太阳内部，就像大地地震学揭示地球内部的信息一样。由于第二阶段将使用的观测仪器和方案相当敏感和复杂，在最终选择六个地点之前，重要的是在全球各地正在考虑的各个地点，包括乌代布尔地点进行某些评估实验。范围：印度科学家在太阳物理领域做出了重大贡献。USO具有独特的地理位置，位于大气相当清晰的区域，并且在全球范围内与图森的NSO大致相反。印度政府(GOI)的支持对实验的成功至关重要。这笔赠款将使美国团队能够进行必要的初步测试，并与GOI谈判不同政府机构提供的必要设施。资金：本项目由以下两项赠款资助：财政年度国家太阳天文台乌代布尔太阳天文台__美元印度货币$印度货币$90 1,130 5,843 20,588 91 2,260 24,933 18,823
