At Camaguey, Cuba, a volcanic aerosol layer was detected at 19-23 km altitude from 18 November through 28 December 1994 (table 2). Backscatter ratios (0.53 µm) were in the 1.26-1.40 range, with integrated backscatter values of 0.18-0.29 x 10-3. These data are similar to those acquired in Cuba during July-October 1994 (Bulletin v. 19, v. 10).
Table 2. Lidar data from Cuba showing altitudes of aerosol layers (bases only). Backscattering ratios are for the Nd-YAG wavelength of 0.53 µm. The integrated value shows total backscatter, expressed in steradians^-1, integrated over 300-m intervals from 16-33 km.
