Resumo

Vertical geomagnetic cutoff rigidities are obtained for the worldwide network of neutron monitors via trajectory calculations for the International Geomagnetic Reference Field (IGRF) for the period of 1950–2020. The results of the calculations indicate a general decrease in the geomagnetic cutoff rigidity at most points due to an overall decrease in the geomagnetic field during the period under consideration. The planetary distribution of the geomagnetic cutoff rigidity until the 2050s is forecast.
