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 …

Executive summary Land and climate interact in complex ways through changes in forcing
and multiple biophysical and biogeochemical feedbacks across different spatial and …

Biogenic vapors form new particles in the atmosphere, affecting global climate. The
contributions of monoterpenes and isoprene to new particle formation (NPF) have been …

Aerosol-cloud interactions remain the largest uncertainty in climate projections. Ultrafine
aerosol particles smaller than 50 nanometers (UAP< 50) can be abundant in 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 …

Cloud condensation nuclei (CCN) can affect cloud properties and therefore Earth's radiative
balance,–. New particle formation (NPF) from condensable vapours in the free troposphere …

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 …

Nucleation and growth of aerosol particles from atmospheric vapors constitutes a major
source of global cloud condensation nuclei (CCN). The fraction of newly formed particles …

New particle formation (NPF) in the tropical upper troposphere is a globally important source
of atmospheric aerosols 1, 2, 3, 4. It is known to occur over the Amazon basin, but the …
