V. О. Barinova and V. V. Kalegaev

The paper deals with the quality assessment and the analysis of possible corrections of the empirical model of the shape and position of the high-latitude boundary of the Earth’s outer radiation belt [2] using the full dataset on the electron fluxes with energy above 100 keV measured in the recent 5 years at the orbit of the Meteor-M No. 2 satellite. The high-latitude boundary of the Earth’s outer radiation belt at the altitude of 800 km is approximated with an elliptic curve in the geomagnetic coordination system with the parameters depending on the universal time (UT effect) and geomagnetic activity (Dst index). The full dataset of intersections of the high-latitude boundary of the Earth’s outer radiation belt by the Meteor-M No. 2 satellite in 2014–2019 was constructed to test the model. The database was utilized to determine errors of the model for various geomagnetic conditions in the magnetosphere and at different magnetic longitudes and to propose ways for its modernization.
