Abstract

This study characterizes the midlatitude ionospheric trough (MIT) using a newly implemented detection method applied to ground-based Global Navigation Satellite System (GNSS) data collected over a solar cycle. The MIT is defined as a region of plasma depletion occurring in the nighttime sub-auroral F-region ionosphere. Subsets of over a decade of GNSS-derived ionosphere total electron content (TEC) data were chosen to distinguish behavior under quiet and active geomagnetic conditions and season. The goals of this paper are to characterize MIT dynamics and demonstrate the capability to produce a running synoptic view of the trough. Detection rate and trough position are statistically quantified and visualized.
