Lidar in Hawaii, Virginia, and Germany continued to detect remnants of the aerosols from the November 1985 eruption of Ruiz (figure 41). Total backscatter over Hawaii increased in late May, as a higher altitude layer, centered around 28 km, became evident. This material lacked the sharp sublayering that generally characterizes fresh aerosols, and no large explosive eruptions have recently been reported.
Smoke from major forest fires in China that started 6 May could be tracked on polar orbiting satellite imagery as it moved over Kamchatka and S of the Aleutian Islands. The maximum altitude reached by the smoke was uncertain.
