ResumoThe evolution of the volcanic debris plume originating from the June 1991 eruption of Mt. Pinatubo has been monitored since its genesis using a ground‐based backscatter lidar facility sited at the Jet Propulsion Laboratory (JPL). Both absolute and relative pre‐ and post‐Pinatubo backscatter observations are in accord with Mie scattering projections based on measured aerosol particle size distributions reported in the literature. The post‐Pinatubo column‐integrated backscatter coefficient peaked approximately 400 days after the eruption, and the observed upper boundary of the aerosol column subsided at a rate of ∼200 m mon −1 .
