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.

Topological Features

We analyzed the problems of formation of the outer radiation belt (ORB) taking into consideration the latest changes in our understanding of the high-latitude magnetospheric topology. This includes strong evidence that the auroral oval maps to the outer part of the ring current, meanwhile the ORB polar boundary maps inside the auroral oval. Our analysis also includes the variation of the plasma pressure distribution and the time of the acceleration of relativistic electrons during geomagnetic storm. It is shown that the maximum of ORB is formed after the geomagnetic storm in the region of plasma pressure maximum. The position of this maximum agrees with the prediction of the ORB formation theory based on the analysis of ring current development during storm. We emphasize the role of adiabatic processes in the ORB dynamics and the importance of the substorm injections during storm recovery phase for the formation of enhanced fluxes of ORB electrons after the storm.
