Titel
Lidar observations of the decline of the El Chichon stratospheric load
Abstract
The eruption of the Mexican volcano El Chichon in April 1982 enhanced the stratospheric aerosol load to a level which so far has not been observed by remote sensing techniques. The ruby lidar system at Garmisch-Partenkirchen (47.5 N, 11.0 E) recorded an increase of integral stratospheric particle backscattering of about two orders of magnitude above the background level of the years 1977/78. At northern midlatitudes backscattering was peaking in January/February 1983, as shown in Figure 1. This paper will discuss the decline of the El Chichon stratospheric perturbation. (IFU)
