IDENTIFICATION OF STRATOSPHERIC AEROSOLS

Abstract

Electron beam microanalyses of stratospheric aerosol collections were conducted in the range of elements from Mg through Zn and were generally performed by driving the sample under the electron beam so that traverses down the center of the length of the sample were described. Calibration studies were performed to relate the observed x-ray intensity of the surface density of the deposited material. Another investigation involved a study of the relation between electron beam size and a determination of the number of larger particles present. The major constituent of the collection in the range of elements investigated was found to be sulfur, probably present as a sulfate. Silicon, iron, and aluminum were also present in smaller, but still significant amounts. (Author)
