The behaviour of galactic cosmic-ray intensity during solar activity cycle 24

E Ross, WJ Chaplin - Solar physics, 2019 - Springer
We have studied long-term variations of galactic cosmic-ray (GCR) intensity in relation to the
sunspot number (SSN) during the most recent solar cycles. This study analyses the time lag …

Volcanic and solar activity, and atmospheric circulation influences on cosmogenic 10Be fallout at Vostok and Concordia (Antarctica) over the last 60 years

A study of heliospheric modulation and periodicities of galactic cosmic rays during cycle 24

P Chowdhury, K Kudela, YJ Moon - Solar Physics, 2016 - Springer
Galactic cosmic rays (GCRs) are energetic, charged particles coming from outside the solar
system. These particles encounter an outward-moving turbulent solar wind with cyclic …
