Abstract
This work is focused on the correlation of ionosphere total electron content (TEC) with solar and geomagnetic activities of the space weather at mid-latitude zone. In our analysis, we investigate the TEC time series obtained from dual-frequency GNSS (Global Navigation Satellite System) observations at three continuous GPS/GNSS stations HOVD (48.00N, 91.66E), CHOB (48.08N, 114.53E) and DALN (43.56N, 104.42) for 2013. The statistical analyses are performed on 15 minute averaged yearly TEC values, which reveal the semi-annual anomaly and high correlation with the activities of the Sun and the rotation of the Earth. Phase overlapping seasonal variations of TEC and Sunspot, and Solar flux (10.7) indices, and Earth rotations (LOD) and Atmospheric angular moment (AAM) are observed in our data analyses. Sudden ionospheric storm changes in TEC with geomagnetic storm induced by the extreme solar flare and 2013 events were investigated. The result shows that GPS derived TEC behaves as an indicator of these events showing sudden increase in TEC during the event.
Highlights
This work is focused on the correlation of ionosphere total electron content (TEC) with solar and geomagnetic activities of the space weather at mid-latitude zone
Days of the sudden ionospheric storms of this year are recorded, and we compared them to magnetic storms and solar activity
We tracked the progress of the 2013 TEC changes at each station to identify the days of the strongest ionospheric storms
Summary
This work is focused on the correlation of ionosphere total electron content (TEC) with solar and geomagnetic activities of the space weather at mid-latitude zone. Sudden ionospheric storm changes in TEC with geomagnetic storm induced by the extreme solar flare and 2013 events were investigated. The TEC values are mainly influenced produced from the Sun. The TEC values are mainly influenced produced from the Sun These are classified as by the following factors: solar wind, changes in positive or negative storms, with positive solar activity, flare in the solar atmosphere, storms having high electron densities and massive solar corona eruptions, high-energy negative storms having low electron densities solar particles, extreme ultraviolet solar [2]. Advances in the mid-latitude ionosphere research have recently drawn great interest and has been actively investigated by many authors [4, 6]
