Ion Velocity Variations Observed at 630 km Altitude Tromsoe UHF Radar

View height profiles of ion velocities at 42m and 32m with contributions from ExB drift and ion upflow. Study time-variations in ion velocity directions like westward, eastward, northward, and southward using data from the Tromsoe UHF radar at 630 km altitude.
