On employing International Reference Field (IGRF) model, vertical cutoff rigidities for the epoch 1995 are computed above several cosmic ray stations at different altitudes. Comparison of the results assuming the Earth’s body both as sphere and ellipsoid is worked out whilst results and effects are compared with the approach based on McIlwains L parameter.

The recent satellite magnetic missions, combined with high quality ground observatory measurements, have provided excellent data for main field modelling. Four different groups submitted seven main-field and eight secular-variation candidate models for IGRF-10. These candidate models were evaluated using several different strategies. Comparing models with independent data was found to be diffic...

[1] To investigate the influence of the magnetic field configuration on large-scale ionospheric electrodynamics, a geomagnetic field coordinate system based on Euler potentials is built for three magnetic field configurations: dipole, tilted dipole, and a revision of the International Geomagnetic Reference Field (IGRF). The two-dimensional ionospheric dynamo equation is expressed in this framew...

Vertical cutoff rigidities derived from the International Geomagnetic Reference Fields (IGRF) are normally used to compute the radiation dose at a specific location and to organize the radiation dose measurements acquired at aircraft altitudes. This paper presents some of the usually ignored limits on the accuracy of the vertical cutoff rigidity models and describes some of the computational ar...

Abstract The International Geomagnetic Reference Field (IGRF) model is a combination of the several models developed by independent groups scientists using different approaches for selection input data and methods calculating harmonic coefficients. This approach allows mutual comparison individual their to obtain most reliable values letter provides brief description building IZMIRAN Earth’s ma...
