Highly oxygenated organic molecules (HOM) are formed in the atmosphere via autoxidation
involving peroxy radicals arising from volatile organic compounds (VOC). HOM condense on …

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 …

Atmospheric new particle formation (NPF) is an important global phenomenon that is
nevertheless sensitive to ambient conditions. According to both observation and theoretical …

Atmospheric aerosols and their effect on clouds are thought to be important for
anthropogenic radiative forcing of the climate, yet remain poorly understood. Globally …

About half of present-day cloud condensation nuclei originate from atmospheric nucleation,
frequently appearing as a burst of new particles near midday. Atmospheric observations …

Although experimental methods can be used to obtain the quantitative kinetics of
atmospheric reactions, experimental data are often limited to a narrow temperature range …

Multiphase chemistry plays a vital role in the Earth system, climate, and health. Chemical
reactions, mass transport, and phase transitions between gases, liquids, and solids are …

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 …

Climate change and air pollution are critical environmental issues both in the here and now
and for the coming decades. A recent OECD report found that unless action is taken, air …

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 …
