Title: Airborne measurements of the size distribution and the condensation and ice nucleating ability of particles produced by AgI containing pyrotechnics and acetone solution burners
Abstract: Airborne measurements using two aircraft were made of the size distribution and nucleating activity of particles generated by both AgI pyrotechnic flares and AgI -NHql acetone solution burners.It was found that the pyrotechnic flares produced particles , .generally larger than 0.1 rn in diameter which were good cloud condensation nuclei.Particles produced by the AgIacetone solution burners were less than 0.1 pm in diameter and, by comparison with the pyrotechnic flares in terns of mass of AgI consumed, relatively inefficient both as'ice nuclei and cloud condensation nuclei.l~attelle ~a c i f ic Northwest laborat6&es9 ~ichlann ~a . . . . . . . .
