Meteor trail advection observed during the 1998 Leonid shower

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