First polar mesosphere summer echoes observed at Davis, Antarctica (68.6°S)
Copyright 2004 by the American Geophysical Union. 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 geographic; 74.6°S magnetic). Observations were obtained using a 55 MHz atmospheric r...
