Summary of LARC Particle Asymptotic Changes From Geomagnetic Reference Field Models: 1955 to 1995
Abstract
A high-order (10th) mathematical model for the quiescent geomagnetic field from Epoch 1955.0 to Epoch 1995.0 was used to calculate the asymptotic directions of vertically incident cosmic ray particles at the LARC location (62 deg 12' 09" S - 58 deg 57' 42" W, South Shetlands King George Island, Fildes Bay Ardley Cove, 40 m a.s.l.). The digital computer-based studies were made at spaced intervals of rigidity in a wide range extending from a value sufficiently high (20.00 GV), such that free particle access is ensured, to a low value at which it may confidently he assumed that access would be forbidden (2.00 GV) for this Antarctic location. A summary of the obtained results is given.
