Benzoic acid is an aromatic carboxylic acid naturally present in plant and animal tissues,
which can also be produced by microorganisms. Benzoic acid and a wide range of …

Sea spray aerosol particles (SSA), formed through wave breaking at the ocean surface,
contribute to natural aerosol particle concentrations in remote regions of Earth's atmosphere …

Atmospheric new particle formation significantly affects global climate and air quality after
newly formed particles grow above∼ 50 nm. In polluted urban atmospheres with 1–3 orders …

The summertime Arctic lower troposphere is a relatively pristine background aerosol
environment dominated by nucleation and Aitken mode particles. Understanding the …

Airborne nanoparticles are receiving growing attention due to their impacts on human
health, air quality, and climate. Additionally, there are increasing applications of aerosol …

Primary marine aerosol (PMA)‐cloud interactions off the coast of California were
investigated using observations of marine aerosol, cloud condensation nuclei (CCN), and …

Ultrafine particles (UFPs) dominate the particle number population in the urban atmosphere
and revealing their chemical composition is important. The thermal desorption chemical …

Marine low clouds strongly influence global climate, and their radiative effects are
particularly susceptible to the concentration of cloud condensation nuclei (CCN). One major …

This chapter reviews the history of the discovery of cloud nuclei and their impacts on cloud
microphysics and the climate system. Pioneers including John Aitken, Sir John Mason …

While new particle formation events have been observed worldwide, our fundamental
understanding of the precursors remains uncertain. It has been previously shown that small …
