L625 Lidar Measurements of Pinatubo Volcanic Cloud at HefeiThe Pinatubo volcano erupted violently between June 9-17, 1991. This eruption was much larger than the El Chichon volcanic eruption in April, 1982. Because of the effects on the global environment, much attention was focused on the measurements of the volcanic cloud. The 84 scattering-ratio profiles of the volcanic cloud have been obtained by our L625 lidar system. The conclusions from studies of the data are: (1) Pinatubo volcanic cloud was present over Hefei after 40 days from eruption; (2) the peak scattering ratio varied violently in July and August of 1991; (3) the height of the peak scattering ratio is between about 18 to 25 km; and (4) since August 28, 1991, the optical depth was about one order of magnitude larger than before the eruption.
