Sodium resonance lidar observations of meteor trails are reported from the 1998 Leonid shower experimental at the Starfire Optical Range Kirtland Air Force Base, NM (35.0º N, 106.5º W ). The lidar was operating in a spatially scanning mode that allowed tracking for up to one half-hour. Three trails are presented here whose motion allowed inference of radial as well as vector wind components and apparent diffusivities. The winds are derived independently using the narrow linewidth sodium (Na) resonance Doppler lidar technique and are compared with the tracking results.
