Anthropogenic emissions and land use changes have modified atmospheric aerosol
concentrations and size distributions over time. Understanding preindustrial conditions and …

Atmospheric nucleation is the dominant source of aerosol particles in the global atmosphere
and an important player in aerosol climatic effects. The key steps of this process occur in the …

About half of present-day cloud condensation nuclei originate from atmospheric nucleation,
frequently appearing as a burst of new particles near midday. Atmospheric observations …

Tropical, temperate, and boreal forests are critical components of the climate system, and
the ecosystem services they provide are essential for our society (Bona n et al., 1992, Bonan …

Aerosol nanoclusters (AN), defined here as molecular aggregates suspended in a gas with
dimensions between 2 and 10 nm, are the link between substances that we think of as …

Fundamental questions remain about the origin of newly formed atmospheric aerosol
particles because data from laboratory measurements have been insufficient to build global …

We present laboratory studies and field observations that explore the role of aminium salt
formation in atmospheric nanoparticle growth. These measurements were performed using …

We present measurements of the distributions of droplet size and charge along with, for
selected droplets, the variation of droplet size and charge with time for electrosprays of …

The secondary organic aerosol (SOA) mass yields from NO3 oxidation of a series of
biogenic volatile organic compounds (BVOCs), consisting of five monoterpenes and one …

Nitrogen oxides are essential for the formation of secondary atmospheric aerosols and of
atmospheric oxidants such as ozone and the hydroxyl radical, which controls the self …
