Popis:	During April 1982, based on filter and impactor samples, we intercepted the plume from the eruption of El Chichon. Our measurements of the trace gases in the plume show no enhancement of carbonyl sulfide (COS) over background. It is apparent from the data that strong vertical mixing occurred during this period. Some of the lowest concentrations of COS to date were measured in the lower polar stratosphere during this mission.
