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 of liquid or solid nanoparticles from gas-phase precursors is a
decisive process in Earth's atmosphere and is considered one of the largest uncertainties in …

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

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 …

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

The large concentrations of ultrafine particles consistently observed at high altitudes over
the tropics represent one of the world's largest aerosol reservoirs, which may be providing a …

Aerosol–cloud interactions (ACI) constitute the single largest uncertainty in anthropogenic
radiative forcing. To reduce the uncertainties and gain more confidence in the simulation of …

Abstract Multiangle Implementation of Atmospheric Correction (MAIAC) is a new Moderate
Resolution Imaging Spectroradiometer (MODIS) algorithm that combines time series …

Airborne observations over the Amazon Basin showed high aerosol particle concentrations
in the upper troposphere (UT) between 8 and 15 km altitude, with number densities …
