Meteor trail observations during the Leonids 1996 and 1998 by groundbased lidar(s) and co-located CCD camera
Abstract
By groundbased lidars, we have performed measurements of the altitude of and abundances of selected metals in meteor trails and by a CCD camera of direction and speed of entering meteoroids during the nights of November 16/17, 1996, November 16/17, 1998, and November 21/22, 1988. All instruments are co-located on the site of the Institute of Atmospheric Physics at Kuehlungsborn, Germany (54xN, 12xE). In November 1996, our observations were performed with only the K lidar and interpreted through appropriate modelling by W.J. McNeil and E. Murad (see J.G.R. 104, 2633, 1999 and the following Workshop paper). Our 1998 observations were performed with the CCD camera and three lidars, the latter measuring simultaneously the atom abundances of Fe, Ca, and K within the trails. Our November 1998 observations have allowed us to identify (at least) two distinct meteor showers, the trails of which differ considerably in their altitude distributions and metal compositions. Also, our 1998 observations shed some new light on the interpretation of our 1996 results.
