Monitoring temporal and spatial variations in galactic cosmic rays (GCRs) in the inner heliosphere from data on cosmogenic radionuclides in freshly-fallen meteorites

Abstract

Meteorite data on monitoring the variations in GCR gradients at 2–4 AU from the Sun over the period 1957–2010 demonstrate the effect of the inversion of solar magnetic fields (SMFs) during the solar maximum periods of 11-year solar cycles on the depth of GCR modulation in the heliosphere.
