The 20 February lidar profile at Hampton, Virginia showed quite uniform aerosol density to 23.5 km altitude. By 6 March, the lidar profile had returned to a more normal shape with a distinct peak. At Mauna Loa, Hawaii, lidar data indicated that the aerosol layer on 19 February terminated at a much lower altitude and had smaller peaks than 5 days earlier; integrated backscattering was nearly halved. No significant increase in backscattering was observed from Garmisch-Partenkirchen, Germany October 1984-January 1985. A second higher-altitude layer was detected in December and January, but maximum backscattering ratios did not increase.
