The authors present information on the scattering properties of the Mt Pinatubo aerosol cloud observed by a shipboard lidar over a 73 day period from 11 July - 21 September 1991. The vessel was primarily in the low latitude 8[degrees]N-43[degrees]S Atlantic Ocean during this period. The ships ability to move allows the detector to sense the physical extent of the cloud. During this period the cloud was primarily at an altitude of 16 to 27 km, it was dispersing in a poleward direction at about 5[degrees] per month, and it exhibited pronounced layered and latitudinal structure. The altitude variation, particularly in the lower latitudes, was periodic, and by a spectral analysis technique the authors were able to extract a zonal wind profile.
