Anew global climatological model of the equatorial ionospheric vertical E×B drift: Integrating ground‐based magnetometer, radar,and satellite datasets.==$Earthand Space Science, 13$==, e2025EA004622. https://doi.org/10.1029/2025EA004622https://hdl.handle.net/20.500.12816/5822We present a new empirical vertical E×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 drift within magnetic latitudes of ±5° and altitudes of about 400–550 km) from the Communications and Navigation Outage Forecasting System (C/NOFS) satellite at different longitude sectors. The relationship between EEJ and C/NOFS vertical E×B drift is developed separately at different longitudes over the globe at coincidental times when both data sets are available. These relationships are then used to estimate continuous vertical E×B drift at each epoch of EEJ observation over the respective longitude sectors during local daytime. The reconstructed vertical E×B drift data are combined with global C/NOFS vertical E×B drifts and JULIA data set to develop a global vertical E×B drift model. Validation using Ion Velocity Meter (IVM) drifts from ICON satellite for January to August 2022 shows that our model improves vertical E×B drift global modeling by over 20% compared to the current climatology representation.application/pdfenghttp://purl.org/coar/access_right/c_abf2https://creativecommons.org/licenses/by-nc-nd/4.0/Equatorial ionosphereVertical E×B driftEquatorial electrojet (EEJ)http://purl.org/coar/resource_type/c_6501https://purl.org/pe-repo/ocde/ford#1.03.05Earthand Space Sciencehttps://doi.org/10.1029/2025EA004622
