Polar mesosphere summer echoes (PMSE) are very strong radar echoes primarily studied in
the VHF wavelength range from altitudes close to the polar summer mesopause. Radar …

Peculiar atmospheric radar echoes from the high‐latitude summer mesosphere have
spurred much research in recent years. The radar data (taken on frequency bands ranging …

Recently we have begun to appreciate more fully the degree and the consequences of
variability in gravity wave (GW) forcing of the middle atmosphere. Such variability arises for a …

A total of 8 sounding rocket flights with measurements of neutral air turbulence in the upper
mesosphere have been performed in the past 10 years with simultaneous and nearly co …

Gravito‐photophoresis, a sunlight‐induced force acting on particles which are geometrically
asymmetric and which have uneven surface distribution of thermal accommodation …

Simultaneous measurements of polar mesosphere summer echoes (PMSE) by a VHF radar
and temperatures in the mesopause region by a potassium lidar were performed on …

It is commonly accepted that the existence of polar mesosphere summer echoes (PMSEs)
depends on the presence of charged aerosols since these are comparatively heavy and …

Polar Mesosphere Summer Echoes (PMSE) have been observed in the high latitudes of the
Northern and Southern Hemisphere for several years using VHF radars located at …

Polar mesosphere summer echoes (PMSE) have been observed for the first time at Wasa,
Antarctica (73° S, 13° W, 61° geomagnetic). A new 54.5 MHz radar, MARA, operated first in …

We report the first observations of polar mesosphere summer echoes (PMSE) above the
high‐latitude Southern Hemisphere (SH) station Davis, Antarctica (68.6° S, 78.0° E …
