Abstract: During February and March 1993, Rayleigh lidar observations of temperature structure and gravity wave activity were carried out in the high Canadian Arctic at Eureka, Northwest Territories (80°N, 86°W). A sudden warming ...

Abstract: Four hundred and twenty-two nights of stratospheric gravity wave observations were obtained with a Rayleigh lidar in the High Arctic at Eureka (80°N, 86°W) during six wintertime measurement campaigns between 1992/93 and ...

Abstract: This paper describes wind measurements derived from displacements of small-scale cloud features obtained from time-lapse videography and simultaneous lidar measurements. Lidar provides the attitude of the cloud feature, ...
