要更好地了解太阳活动周期及其对太阳输出的影响,首先需要更多关于其过去行为的信息。这笔赠款是为了完成RISE(太阳对地球的辐射输入)计划的一个方面,以减少和减少1915年至1985年期间在Mt.威尔逊这些图像提供了迄今为止最长的太阳色球谱斑记录。我们还计划分析这些结构在过去7个太阳活动周期中在活动区域和网络中的行为,以获得有关太阳紫外线,EUV和总辐照度变化的信息。光斑面积,空间分布和亮度的行为也将提供关于太阳磁场和活动水平的信息,这些信息与太阳黑子指数和其他更短的数据库(如磁图)获得的数据互补。这笔赠款的数据将提供给科学界。这一项目的结果应引起高层大气物理学家、气候学家的极大兴趣,并有助于不断努力改进对太阳活动周期的预测和动态了解。
英文摘要
Improved understanding of the solar activity cycle and of its effects upon solar outputs requires, first and foremost, more information on its past behavior. This grant is for the completion of one aspect of the RISE (Radiative Inputs of the Sun to Earth) program, to digitize and reduce the CaK spectroheliograms obtained on a daily basis between 1915 and 1985 at Mt. Wilson. These images provide by far the longest record of solar chromospheric plages. We also plan to analyze the behavior of these structures in active regions and in the network over the past 7 solar cycles, for information on variations of solar UV, EUV and total irradiances. The behavior of facular area, spatial distribution, and brightness will also provide information on the sun's magnetic fields and activity levels that is complementary to data obtained by the sunspot index, and from other much shorter data bases such as magnetograms. The data from this grant will be made available to the scientific community. The results of this project should be of considerable interest to the upper atmospheric physicists, climatologists and in ongoing efforts to improve prediction and dynamical understanding of solar activity cycles.
