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 (NPF) is the source of over half of the atmosphere's cloud
condensation nuclei, thus influencing cloud properties and Earth's energy balance. Unlike in …

Environmental context Aerosol water-soluble organic carbon is a complex mixture of
thousands of organic compounds which may have a significant influence on the climate …

Six years of aerosol size distribution measurements between 20 and 600 nm diameters and
total aerosol concentration above 10 nm from March 2008 to February 2014 at the high …

We have analysed the trends of total aerosol particle number concentrations (N) measured
at long-term measurement stations involved either in the Global Atmosphere Watch (GAW) …

Measurements are presented showing the presence of biological material within frequent
dust storms in the western United States. Previous work has indicated that biological …

La Paz and El Alto are two fast-growing high-altitude Bolivian cities forming the second
largest metropolitan area in the country, located between 3200 and 4050 m asl Together …

Secondary aerosols formed from anthropogenic pollutants and natural emissions have
substantial impacts on human health, air quality, and the Earth's climate. New particle …

New particle formation (NPF) was predicted to contribute to a major fraction of free
tropospheric particle number and cloud condensation nuclei (CCN) concentrations by global …
