Characteristics of the wind, temperature and PMSE field above Davis, Antarctica
Polar Mesosphere Summer Echoes (PMSE) were detected above the high-latitude station Davis, Antarctica (68.6°S) using a 55 MHz atmospheric radar during the 2003–2004 austral summer. In this paper, we examine the characteristics of southern hemisphere PMSE events observed during the interval 19 Novemb...
