Three independent techniques for measuring wind in the mesosphere and lower thermosphere region were compared using simultaneous measurements during the period May 1997 to April 1998. The three instruments used, a Fabry-Perot spectrometer, a medium frequency radar, and a meteor radar, are located on New Zealand's South Island. The results obtained during this investigation show reasonable agreement amongst the three methods, in particular between the Fabry-Perot and the meteor radar. Correlation analysis of the meteor radar height-resolved winds and the Fabry-Perot spectrometer winds provides a valuable method for determining airglow heights. The results from the height determinations show a yearly variation of the OH emission layer, with its lowest height during summer, while the OI emission layer is found to remain at a relatively constant height. ¿ 1998 American Geophysical Union
