Abstract content

The relationship of long-term cosmic ray modulation with solar activity parameters such as sunspot group number, their average heliolatitude, tilt of current sheet, and solar magnetic field strength is analyzed. The period of 1957 - present time is under consideration. We have used cosmic ray data obtained in the atmosphere at polar and middle latitudes and the neutron monitor data. It is shown that there is a negative trend of the cosmic ray flux observed.
