AGASP II arctic haze aerosol characteristics—Influence of volcanic eruption emissions

Abstract

Possible intrusion of eruption material from the 1986 eruptions of Augustine volcano into Arctic Haze measurements is considered by comparing haze samples collected directly in the eruption plume. Based on aerosol particle size distribution, particle characteristics, and relative locations of the eruption plume and the haze sampling flight paths it is concluded that intrusion might have occurred during three of the haze flights cited here, but only to a very slight extent, affecting only the larger size particles which constitute a few percent of the total haze aerosol mass.
