Hale cycle and long-term trend in variation of galactic cosmic rays related to solar rotation

Mursula, K.; Gil, A.

Context. Galactic cosmic ray (GCR) intensities around solar minimum times are modulated by magnetic drifts that depend on the overall solar polarity. GCR intensities reach a higher but more narrow peak during negative minima than during positive minima. However, despite these higher intensities, the variation of GCRs over timescales of solar rotat…
