Atmospheric aerosols from human activity influence climate. Uncertainties in the understanding of their effects limit our knowledge about climate change. Aa Aa Aa What is the source and ...

Aerosols vary in composition, size, concentration, and source. They profoundly affect climate, visibility, human health, and biogeochemical cycling. Particle sizes are determined by the mechanism ...

Aerosols are colloidal systems comprised of mesoscale solid or liquid particles (with diameters ranging from 10 nm to 100 µm) suspended in a gas. They are pervasive in our atmosphere and their sources ...

Aerosols are a key mediator of poor air quality and respiratory and cardiac health outcomes. Improving human health depends on insights from aerosol science on emission sources and transport, ...

For instance, the formation of aerosol particles (“hazes”) may affect the surface ultraviolet radiation flux and temperature and may serve as a source of complex organic molecules including nutrients.

An international study led by researchers at the Paul Scherrer Institute PSI has used a new method to identify the various sources of aerosols that create smog in Beijing. In a collaboration with ...

A research team led by EPFL scientists has developed a system that provides key insight into the relationship between sea ...

The Atmospheric Aerosols group operates within the Institute for Atmospheric and Earth System Research (INAR) at University of Helsinki, Faculty of Science. We perform both long-term and campaign-wise ...

CAICE is a Center for Chemical Innovation focused on the fundamental chemistry behind the impact of aerosol particles on our climate. Studies fundamental physical processes that govern terrestrial ...

The EU-funded PAREMPI project aims to thoroughly investigate exhaust emissions from the transport sector—not only the ...

Over the past four years, at least three key studies aimed at real-time pollution source identification have either been ...
