Lidar data from Mauna Loa, Hawaii continued to show a gradual decline in stratospheric aerosols (figure 49). Integrated backscattering on 24 November was the lowest measured since the 1982 increases associated with the eruptions of El Chichón and the "Mystery Cloud" (probably from the initial explosive phase of the December 1981-January 1982 Nyamuragira eruption in Zaire). Values measured in Virginia and Germany remained relatively stable. The low integrated backscattering recorded 9 October off the coast of North Carolina was attributed at least partly to the high tropopause that night.
