Leonid activity profiles obtained from one airborne and two ground-based intensified video cameras, which observed both peaks of the 2001 Leonid meteor storm, are analyzed. After corrections for the topocentric time of the stream encounter, radiant altitude, and detection efficiency of the camera system, we find that the Asian storm peak caused by the 4-revolution dust trail with maxima at 10h43m and 11h02m UT. The airborne data set indicates an earlier second Asian peak at 17h39m UT, but to link this peak to the passage of the 9-revolution trail is questionable. Whereas the peak times and the peak activity ratio between both storms agree well with the global analysis of the visual observations, we find a much lower population index on the order of r=1.35 for faint meteors.
