Earth and Space Science, Volume 13, Issue 4, April 2026.Abstract We present a new empirical vertical E×B $\mathbf{E}\times \mathbf{B}$ drift model developed using ground‐based magnetometer, radar, and satellite data over equatorial latitude regions. We first implement an algorithm relating magnetometer derived equatorial electrojet (EEJ) and vertical ion plasma drift (equivalent to vertical E×B $\mathbf{E ...
