The present paper reviews existing knowledge with regard to Organic Aerosol (OA) of
importance for global climate modelling and defines critical gaps needed to reduce the …

Deliquescence relative humidity (DRH) and efflorescence relative humidity (ERH), the two
parameters that regulate phase state and hygroscopicity of substances, play important roles …

Interactions with water are crucial for the properties, transformation and climate effects of
atmospheric aerosols. Here we present a conceptual framework for the interaction of …

Laboratory studies of liquid–liquid phase separation in particles containing organic species
and inorganic salts of atmospheric relevance are reviewed. The oxygen-to-carbon elemental …

The rise of ammonia emissions in Asia is predicted to increase radiative cooling and air
pollution by forming ammonium nitrate particles in the lower troposphere. There is, however …

Deliquescence is a first order phase transition from solid to solution that occurs at a relative
humidity (RH) that is characteristic to the solid ingredient. In blends containing more than …

Aerosol hygroscopicity strongly influences the number size distribution, phase state, optical
properties, and multiphase chemistry of aerosol particles. Due to the large number of …

Measurements of the reactive uptake coefficient for N2O5 hydrolysis, γm, on sub-micron
organic aerosols were performed in an entrained aerosol flow tube as a function of relative …

Chemical mechanisms for the production of secondary organic material (SOM) are
developed in focused laboratory studies but widely used in the complex modeling context of …

The ability of sub-micron-sized organic acid particles to act as cloud condensation nuclei
(CCN) has been examined at room temperature using a newly constructed continuous-flow …
