The PI will build on previous work improving the understanding of the role of photospheric magnetic activity in determining solar irradiance variation. The main objectives are: (1) improving empirical models of variations in total irradiance using the digital, full-disc CaK images produced from the Mount Wilson daily spectroheliograms obtained between 1915 and 1985; (2) using these digital CaK data to produce the first empirical models of long-term solar spectral irradiance variations in the ultraviolet and extreme ultraviolet, extending back to 1915; (3) extending digitization of the Mount Wilson data to include plates of different format obtained between 1905 and 1915; and (4) extending previous study of the behavior of plages and spots at times of highest solar activity.

PI将建立在以前的工作，以提高对光球磁活动在确定太阳辐照度变化方面的作用的理解。主要目标是：（1）利用从1915年至1985年期间获得的威尔逊山每日分光日像图产生的数字化全圆盘CaK图像改进总辐照度变化的经验模型;（2）利用这些数字化CaK数据产生第一个紫外和极紫外长期太阳光谱辐照度变化的经验模型，可追溯到1915年;（3）扩展威尔逊山数据的数字化，以包括1905年至1915年期间获得的不同格式的板块;（4）扩展先前对太阳活动最高时期的谱斑和斑点行为的研究。
