Oksavik et al., JGR 2006

Temperature Gradient Instability Onset

2200-0000 UT: Poleward motion of ocean scatter footprint following sunset.0000-0120 UT: Irregularities form in post-sunset ionosphere. Possibly associated with F-region gradient drift instability as reported previouslygradient-drift instability as reported previously.0120 UT onwards: Temperature gradient reverses and steepens. Backscatter intensifies. Onset of TGI.
