Surface area and mass of stratospheric aerosols generated by the June 1991 eruption of Mt. Pinatubo have been estimated by means of a statistical aerosol model applied to midlatitude lidar observations. Surface area results agree well with equivalent ones obtained by balloon-borne particle counters. These observations indicate that ozone destruction induced by heterogeneous chemical reactions proceeding on Mt. Pinatubo aerosols should persist at least until mid-1993. Lidar-derived aerosol loads for Mt. Pinatubo are presented and compared to the ones recorded after the 1982 eruption of El Chichon. Over a two-year period past the eruption the column mass of the Pinatubo cloud was 2–3 times larger than the El Chichon one.
