Abstract
The earlier proposed hypothesis (Zuev et al., 2014) about the possibility of nanodispersed black carbon particles formation in eruptive column of volcanic eruption with VEI ³ 4 is discussed. The probable characteristics of volcanogenic soot particles and their distinctive features from stratospheric black carbon particles of other origin are analyzed. A brief review of suitable instrumental methods for detecting particles is carried out, and observational facts that indicate the possible detection of particles of volcanic soot earlier are presented. The idea of a complex experiment for observational confirmation of the hypothesis is proposed.
