Measuring meridional mesospheric winds with the AMOR meteor radar

The amor meteor radar can measure meridional winds in the meteoric region o f 80-120 km with excellent spatial resolution. This paper gives details of the Doppler section of the amor system. Analysis techniques are described t hat enable the use of very short-lived echoes, which when combined with the high sensitivity of the amor radar provides a large data set of wind measu rements. Results for a 5 day period are presented at various heights indica ting a vertically propagating semi-diurnal. tide. (C) 2000 Elsevier Science Ltd. All rights reserved.
