摘要：

A technique has been developed that will transfer the Tsyganenko 1989 modulation for cutoff rigidity values to different epochs of the International Geomagnetic Reference Field (IGRF). The technique separates the effect of the Tsyganenko external currents on cutoff rigidity values previously calculated at 450 km using the 1995 IGRF such that these effects can be applied to other models of the IGRF. The Tsyganenko modulation effects were then applied to the 2020 internal field model. Two improvements to the original set of calculations include a three-point longitudinal smoothing to reduce the unevenness of the penumbral effects and a replacement of the original -100 Dst values for Kp values > 5 to -50 Dst increments. These changes have extended the original library of 88 world grids to a total of 128 world grids of cutoff rigidity values that are applicable for all Kp values (0-9 + ) and Dst values to -500 nT.
