Lidar measurements of stratospheric aerosols from Mount Pinatubo at Camaguey, Cuba

Lidar measurements of stratospheric aerosols made at Camaguey, Cuba 21°N, six months after Mount Pinatubo eruption, show a very large increase in the stratospheric aerosol burden. Peak scattering ratios greater than 20 have been observed in early January 1992. In the same month integrated backscattering in the layer between 16 and 33 km shows a maximum value larger than 5 × 10−3 sr−1. The course of those parameters such as the height of peaks and of the layer base between January 1992 and November 1993 is shown.
