The authors report on lidar observations of volcanic aerosols made at Amudsen-Scott, South Pole, during September 1991 to June 1992. Two major eruptions occured during 1991, Mt. Pinatubo in the Philippines, and Mt. Hudson in Chile. The stratospheric cloud formed by gas-to-particle interactions was inhibited from spreading over the south pole by the polar vertex, but was able to spread into this area in the spring. Measurements were made of integrated backscatter and of the aerosol mass loading and are reported in the paper.
