Recent lidar measurements at Hampton, Virginia (37.1N, 76.3W) indicate that the current mid-latitude stratospheric aerosol level, after recovery from the 1991 eruption of Mount Pinatubo, is lower than the background level measure during the vocanically quiescent period in 1979. This suggests that perhaps the natural stratospheric aerosol background may be lower than previously thought. Volcanically inactive periods, such as the periods after the 1982 El Chichon eruption and again after the 1991 Pinatubo eruption, provide opportunities to study long-term trends in volcanic aerosol decay. And, the present state of very low aerosol loading in the stratosphere, provides opportunities to study and gain a better understanding of the natural background aerosol.
