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⁺.

太阳磁场逆转期间地球外层的离子组成

摘要

本文分析了2009年至2018年期间810-830 km高度的高层大气离子组成的测量数据；测量是通过搭载Meteor-M no。1号航天器的RIMS质谱仪进行的。1号和流星M号。2.考虑到太阳磁场反转期间的太阳活动（沃尔夫数），分析了O ⁺浓度的时空变化。结果发现，太阳的磁场反转发生在第24个太阳周期的太阳最大值期间，并且伴随着O ⁺浓度的显着增加。
