SunRISE: Precision Photometric Measurements of Solar-Cycle Changes in the Sun's Luminosity

这个项目继续精确测量太阳表面大范围的亮度变化。PI通过大熊太阳天文台的太阳圆盘光度计获取数据，主要是为了更好地了解太阳辐照度变化的漫射成分。这是太阳辐射输出的长期太阳周期调制的主要因素之一。PI继续这项研究将允许对即将到来的从太阳最小值到最大值上升的精确光度测量进行分析，这对于理解太阳周期辐照度的变化非常重要。长期辐照度变化对地球的影响可能比任何其他太阳现象都要深远。

This project continues to precisely measure large-scale solar surface brightness variations across the solar disk. The PI acquires data with the Solar Disk Photometer at Big Bear Solar Observatory, principally to better understand the diffuse component of the solar irradiance variations. This is one of the main elements responsible for the long-term solar cycle modulation of the Sun's radiative output. The PI's continuation of this research will allow analysis of upcoming precision photometric measurements of the rise from solar minimum to maximum, important for understanding solar-cycle irradiance variations. Long-term irradiance variations could impact the Earth more profoundly than any other solar phenomenon.
