太阳辐照度的太阳周期变化

Solar cycle variation in solar irradiance

K. L. Yeo, N. A. Krivova, S. K. Solanki

摘要:

过去40年从空间进行的大量测量表明,太阳辐照度与11年太阳活动周期之间存在着明显的相关性。将太阳辐照度变化与光球磁性联系起来的模型在解释这些观测中的大多数明显趋势方面取得了重大进展。然而,在绝对辐射测量、长期变化和太阳周期变化的光谱依赖性方面,不同的测量和模型之间存在持续的差异。我们提出了太阳辐照度测量和模型的概述,并讨论了调和两者之间的分歧的关键挑战。

英文摘要:

The correlation between solar irradiance and the 11-year solar activity cycle is evident in the body of measurements made from space, which extend over the past four decades. Models relating variation in solar irradiance to photospheric magnetism have made significant progress in explaining most of the apparent trends in these observations. There are, however, persistent discrepancies between different measurements and models in terms of the absolute radiometry, secular variation and the spectral dependence of the solar cycle variability. We present an overview of solar irradiance measurements and models, and discuss the key challenges in reconciling the divergence between the two.
