Scientific paper

Measurements using balloonborne optical particle counters at Laramie, Wyoming during the summer of 1991 are used to study the particle-size distribution and volatility of the aerosol which formed in the stratosphere following the mid-June eruptions of Mt. Pinatubo. Enhanced aerosol layers were observed below 20 km as early as 16 July, about 1 month after the eruption. During late July, a transient though substantial particle layer was observed in the 23 km region. High concentrations of large particles in this high-altitude layer resulted in aerosol-mass mixing ratios as large as 0.5 ppm, considerably larger than observed following the eruption of El Chichon. Aerosol volatility tests indicated that well over 90 percent of the particles were composed of an H2SO4/H2O solution in all layers observed, indicating rapid conversion of SO2 to H2SO4 and subsequent droplet growth. High concentrations of droplets suggest homogeneous or ion nucleation as the most likely aerosol-production mechanism.
