Recent interest in stratospheric chemistry, sparked in part by the suggested roles of atomic chlorine (Cl) and nitrogen oxides (NO/sub x) in the catalytic destruction of ozone (O/sub 3/), has made sampling and measurement of trace constituents above the tropopause highly desirable. An ongoing research program that carries out aircraft and balloon-borne stratospheric chemical sampling at regular intervals by using chemically impregnated filters to collect particles and reactive gases is discussed.
