原始语种摘要: New particle formation, which greatly influences the number concentrationsand size distributions of an atmospheric aerosol, is often followed by arapid growth of freshly formed particles. The initial growth of newlyformed aerosol is the crucial process determining the fraction of nucleatedparticles growing to cloud condensation nuclei sizes, which have asignificant influence on climate. In this study, we report the laboratoryobservations of the growth of nanoparticles produced by nucleation ofH2SO4 and water in a laminar flow tube at temperatures of 283, 293and 303 K, under dry (a relative humidity of 1%) and wet conditions(relative humidity of 30%) and residence times of 30, 45, 60 and 90 s.The initial H2SO4 concentration spans the range from 2...
