Abstract

The heliospheric modulation potential was reconstructed based on data from the North Greenland Ice Core Project (NGRIP) on the content of the cosmogenic isotope ¹⁰Be in the Greenland ice from the end of the 14th century CE. This time interval includes global solar-activity minima, such as the Spörer (≈1460–1550 CE), Maunder (≈1645–1715 CE), and Dalton (≈1790–1830 CE) minima. The reconstruction results show that, although the duration of the Dalton minimum is small, the depth of the Maunder minimum could be comparable to the depth of the Dalton minimum. The Spörer minimum may be less deep than the Maunder minimum.

从14世纪末以来基于格陵兰冰中宇宙成因同位素10 Be的含量和太阳活动极端性的数据重建太阳圈调制势

摘要

根据北格陵兰冰芯计划（NGRIP）的数据，从14世纪末以来格陵兰冰中的宇宙成因同位素¹⁰ Be的含量，重建了太阳圈的调制势。该时间间隔包括全球太阳活动最小值，例如Spörer（≈1460–1550 CE），Maunder（≈1645–1715 CE）和Dalton（≈1790–1830 CE）最小值。重建结果表明，尽管道尔顿最小值的持续时间很小，但是Maunder最小值的深度可以与道尔顿最小值的深度相当。Spörer最小值可能比Maunder最小值深。
