Stratospheric aerosols continued their descent toward background levels in February. Lidar data at Mauna Loa, Hawaii were similar to those of the previous month. The long-term trend in integrated backscattering at Hampton, VA shows a continuing irregular decline since the maximum reached shortly after the 1982 El Chichón eruption. However, values remained slightly higher than during the period of relative atmospheric quiet in the late 1970's, ended by the May 1980 eruption of St. Helens.
