| Abstract | As part of the Green Ocean Amazon (GoAmazon) field campaign in Brazil, the US Department of Energy G-1 aircraft was deployed to make semi-Lagrangian measurements of aerosols and trace gases over and downwind of Manaus, with the objective of investigating the interactions between urban and biogenic emissions. Here we focus on the rapid growth of anthropogenic ultrafine aerosols observed in the Manaus plume on 13 March 2014. Observations indicate that the ultrafine particles rapidly grew from about 20 nm to 50 nm at a sustained average rate of 11 nm h-1 largely due to secondary organic aerosol (SOA) formation from oxidation of biogenic volatile organic compounds. Lagrangian box model analysis of the evolving number and volume size distributions indicate that SOA growth kinetics was dominated by condensation of semivolatile organic compounds (SVOCs). Although SVOCs are conventionally assumed to equilibrate with organic aerosol mass and thereby promote the growth of large particles, our analysis shows that dynamic partitioning of SVOCs, with hindered uptake by large semisolid particles, facilitates the growth of small particles. We further demonstrate, via cloud-resolving model simulations, that the grown ultrafine particles significantly increase shallow cloud coverage and alter their droplet size distribution, suppress rain formation and enhance the vertical development of shallow clouds early in the cloud lifecycle, then augment the transition of shallow to deep convective clouds. These findings have important implications for representing SOA formation and phase-dependent particle growth mechanisms in aerosol-climate models. | |||
