An overview of the Davis station hydroxyl airglow temperature program will be given. Seasonal structure, planetary scale periodicities and inter-year variability determined from six years of hydroxyl airglow rotational temperatures will be presented. Solar cycle influences will be examined.
Noctilucent ("night shining") clouds can be a beautiful, awe-inspiring sight but they are viewed by some scientists as harbingers of mans impact on his environment. We use a rare sighting of a noctilucent cloud at Davis station (68.6S, 78.0E)…
High-resolution Fabry-Perot spectrometer observations of the OH(62) Q1(1) line, l834.46 nm, were made at Mawson, 67.6ºS 62.9ºE, and Davis, 68.6ºS 78.0ºE, Antarctica, in 1997. The observing program resulted in three sets of continuous OH observations suitable for tidal analysis: July 25…
Ground-based Fabry-Perot spectrometer observations from the Australian Antarctic stations of Davis and Mawson show an upward wind ~100 m s-1 in the thermosphere at ~240 km altitude on the night of Day of Year 159 in 1997.
The thermopheric oxygen l630 nm emission has been observed using high-resolution Fabry-Perot spectrometers at Mawson (67.6°S, 62.9°E) and Davis (68.6°S, 78.0°E), Antarctica. A new technique, combining the results from the two instruments, is used to derive vector wind fields.
