Abstract

Atmospheric nanoparticles can significantly influence Earth’s climate if they grow to sizes large enough to nucleate cloud droplets. While the contribution of extremely low volatility vapors to nanoparticle growth has been discussed extensively, the role of semivolatile organics has been largely overlooked. Here we examine the growth and impacts of air pollution nanoparticles from an isolated metropolis amidst the Amazon rainforest. Although extremely low volatility organics are necessary for the initial growth of nanoparticles, model analysis suggests that dynamic gas-particle partitioning of semivolatile oxidation products of anthropogenic and natural hydrocarbons is predominantly responsible for the observed rapid growth to 50 nm. Furthermore, cloud-resolving simulations demonstrate that the grown particles appreciably modify shallow cloud droplet size distribution, suppress precipitation, and enhance the transition to deep clouds. With condensable semivolatile organics typically formed in greater proportion, similar nanoparticle growth and impacts on clouds could likely occur in heavily urbanized forested regions globally.

Rapid growth of anthropogenic organic nanoparticles greatly alters cloud life cycle in the Amazon rainforest

Journal Article Zaveri, Rahul A. ; Wang, Jian ; Fan, Jiwen ; ... - Science Advances

Aerosol-cloud interactions remain uncertain in assessing climate change. While anthropogenic activities produce copious aerosol nanoparticles smaller than 10 nanometers, they are too small to act as efficient cloud condensation nuclei (CCN). The mechanisms responsible for particle growth to CCN-relevant sizes are poorly understood. Here, we present aircraft observations of rapid growth of anthropogenic nanoparticles downwind of an isolated metropolis in the Amazon rainforest. Model analysis reveals that the sustained particle growth to CCN sizes is predominantly caused by particle-phase diffusion-limited partitioning of semivolatile oxidation products of biogenic hydrocarbons. Cloud-resolving numerical simulations show that the enhanced CCN concentrations in the urbanmore »« less

Volatile monoterpene ‘fingerprints’ of resinous Protium tree species in the Amazon rainforest, Phytochemistry: Data

Dataset Jardine, Kolby

This data package contains data used in the publication, "Volatile monoterpene ‘fingerprints’ of resinous Protium tree species in the Amazon rainforest. Phytochemistry. 2019 Apr 1;160:61-70." Data was collected from species within the NGEE Tropics site in Manaus, Brazil. Included are volatile monoterpene compositions of tree trunk resins from 15 tree species among 77 individuals belonging to the genus Protium. We hypothesized that by normalizing the abundances of 28 monoterpenes in each individual, a unique Protium monoterpene ‘fingerprint’ pattern exists for each of the 15 species.
