Using two geomagnetic observation data sets over Indian sector, we analyze the long\u2010term trend of the monthly\u2010median equatorial electrojet (EEJ) in 1967\u20132015 after removing the solar activity and seasonal signals. During 1967\u20131999, a period of slow geomagnetic\u2010equator motion, the residual of the EEJ shows a decreasing trend between 09 and 13 LT and an increasing trend between 13 and 16 LT. Following accelerated geomagnetic\u2010equator motion after 1999, the afternoon enhanced trend is suppressed, whereas the morning decreased trend is strengthened for the full\u2010period (1967\u20132015) data set. The semidiurnal\u2010like pattern in the EEJ long\u2010term trend is possibly related to the weakened migrating semidiurnal tide (SW2) caused by the enhanced greenhouse gases as reported in previous studies. Our results disentangle the influences of greenhouse gas and geomagnetic secular variation on equatorial ionospheric electrodynamics, and have potential implications for ionospheric climate and weather.<\/jats:p>","DOI":"10.1029\/2026gl126510","type":"journal-article","created":{"date-parts":[[2026,10,23]],"date-time":"2026-10-23T09:45:32Z","timestamp":1792748732000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The
