Recent studies reveal that midlatitude ionospheric irregularities are less understood due to lack of models and observations that can explain the characteristics of the observed wave structures. In this paper, the Temperature Gradient Instability (TGI) and the Gradient Drift Instability (GDI) are analyzed as the cause of the midlatitude irregularities. Based on co-located experimental observations...
Joint measurements by the Blackstone SuperDARN radar, and the Millstone Hill Incoherent Scatter Radar (ISR) are analyzed to investigate the generation source responsible for the observed decameter-scale irregularities in the nightside sub-auroral ionosphere during quiet and active geomagnetic periods. In this work, the Temperature Gradient Instability (TGI) and the Gradient Drift Instability (GDI)...
The mid-latitude SuperDARN radars have identified quiet-time decameter-scale density irregularities in the night-side sub-auroral ionosphere that have been proposed to be responsible for the observed low-velocity Sub-Auroral Ionospheric Scatter (SAIS). The physical mechanism responsible for such common irregularities is still unknown. Joint collaborative experiments using the SuperDARN HF radar located...
SuperDARN HF radars regularly observe decameter-scale ionospheric irregularities at mid-latitudes during quiet geomagnetic conditions. The mechanism responsible for the growth of such common irregularities is still unknown. Previous joint measurements by Millstone Hill Incoherent Scatter Radar (ISR) and SuperDARN HF radar located at Wallops Island, Virginia have identified the presence of opposed...
