太阳变率对气候的影响目前尚不确定。最近的观测表明，太阳调制宇宙射线对全球云层的影响可能是一种机制。令人惊讶的是，太阳变率的影响在低云（小于或等于 3 公里）中最强，这表明涉及气溶胶形成的微物理机制，宇宙射线电离增强了气溶胶的形成。如果得到证实，这表明日光层的平均状态对地球气候很重要。
The influence of solar variability on climate is currently uncertain. Recent observations have indicated a possible mechanism via the influence of solar modulated cosmic rays on global cloud cover. Surprisingly the influence of solar variability is strongest in low clouds (less than or equal to3 km), which points to a microphysical mechanism involving aerosol formation that is enhanced by ionization due to cosmic rays. If confirmed it suggests that the average state of the heliosphere is important for climate on Earth.
