AB - <jats:title>Abstract</jats:title> <jats:p> Ionospheric Total Electron Content disturbances (dTEC) in the Ultra Low Frequency (ULF, timescales 10 min) range can be driven from below by processes at Earth's surface and lower atmosphere and from above by magnetospheric processes. Using magnetospheric satellite magnetometer, groundbased magnetometer, and dTEC measurements in the auroral zone, Hartinger et al. (2025), <jats:ext-link xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="https://doi.org/10.1029/2024ja033456">https://doi.org/10.1029/2024ja033456</jats:ext-link> showed that over much of the Pc35 band (∼2–50 mHz) ULF waves routinely drive dTEC perturbations correlated with magnetic field disturbances (dBground), suggesting dTEC could be used as a ULF wave diagnostic. Motivated by the significant differences expected for magnetosphere, ionosphere, atmosphere, and ground properties at a different latitude, we extend Hartinger et al. (2025), <jats:ext-link xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="https://doi.org/10.1029/2024ja033456">https://doi.org/10.1029/2024ja033456</jats:ext-link> to examine midlatitude ( degrees magnetic latitude) dTEC during conjunctions with the Van Allen Probes satellites, a ground magnetometer, and a Global Navigation Satellite System receiver. Consistent with the auroral zone, we find that dTEC often has a corresponding dBground signature, and that dTEC and dBground are well correlated with results dependent on the component of the magnetic field. We also find that dTEC amplitudes are lower (0.5 TECU) and tend to occur at higher frequencies than in the auroral zone, as expected for magnetospheric Pc35 wave latitude dependence. In contrast to the auroral zone, we find that dTEC power does not have
