Thermospheric wind field over Mawson and Davis, Antarctica; simultaneous observations by two Fabry-Perot spectrometers of l630 nm emission. Journal of Atmospheric and Solar-Terrestrial Physics., 1999 (Ref: 8818)
Category 1: Peer-reviewed literature

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.
