This review focuses on the observed characteristics of atmospheric new particle formation
(NPF) in different environments of the global troposphere. After a short introduction, we will …

New particle formation (NPF) represents the first step in the complex processes leading to
formation of cloud condensation nuclei. Newly formed nanoparticles affect human health, air …

New particle formation has been estimated to produce around half of cloud‐forming particles
in the present‐day atmosphere, via gas‐to‐particle conversion. Here we assess the …

Aerosol particles in the atmosphere profoundly influence public health and climate. Ultrafine
particles enter the body through the lungs and can translocate to essentially all organs, and …

A major fraction of atmospheric aerosol particles, which affect both air quality and climate,
form from gaseous precursors in the atmosphere. Highly oxygenated organic molecules …

New particle formation in the upper free troposphere is a major global source of cloud
condensation nuclei (CCN),,–. However, the precursor vapours that drive the process are …

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

Highly oxygenated organic molecules (HOMs) contribute substantially to the formation and
growth of atmospheric aerosol particles, which affect air quality, human health and Earth's …

New particle formation (NPF) studies in China were summarized comprehensively in this
paper. NPF frequency, formation rate, and particle growth rate were closely compared …

Controls on pristine aerosol over the Southern Ocean (SO) are critical for constraining the
strength of global aerosol indirect forcing. Observations of summertime SO clouds and …
