Unusual Radar Echo from the Wake of Meteor Fireball in Nearly Horizontal Transits in the Summer Polar Lower-Thermosphere
The summer polar lower thermosphere (90-100 km) has an interesting connection to meteors, adjacent to the mesopause region attaining the lowest temperature in summer.Meteors supply condensation nuclei for charged ice particles causing polar mesospheric summer echoes (PMSE).We report the observation of meteor trail with nearly horizontal transit at
