A balloon‐borne submicron aerosol counter was successfully flown on three stratospheric balloon experiments over Holloman Air Force Base, New Mexico, in May 1973. The results indicate that particulate matter at altitudes above 23km has markedly different scattering parameters from particles at lower levels. This effect is manifested in the form of increasingly steeper size distributions and a lack of particles larger than 0.4µm diameter. The extent to which these features are attributable either to nonspherical particles or to particle index of refraction uncertainties rather than to the actual size distribution, is a matter of conjecture at this time.
