Abstract

This paper analyzes measurement data on the ionic composition of the upper atmosphere at altitudes of 810–830 km in the period from 2009 to 2018; the measurements were made with RIMS mass spectrometers onboard the space vehicles Meteor-M no. 1 and Meteor-M no. 2. The spatial–temporal variability of the O+ concentration is analyzed in view of the solar activity (Wolf numbers) during a reversal of the solar magnetic field. It is found that the Sun’s magnetic field reversal occurred during the solar maximum of the 24th solar cycle and was accompanied with a significant increase in the concentration of O+.
