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 ...

It also has a thick atmosphere, veiled by dense aerosols, that seemed impenetrable — until now. With the cutting-edge ...

The Scripps O 2 Program measures changes in atmospheric oxygen levels from air samples collected at stations around the world. CAICE is a Center for Chemical Innovation focused on the fundamental ...

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 ...

Atmospheric aerosols compete with carbon dioxide as an agent of warming. In the charge against global warming, carbon dioxide has long held sway as public enemy number one. But now, less ...

Unraveling the chemical processes in soot particle filters reveals new ways to produce synthetic fuels.

This work also yielded key parameters required to understand the role of cloud and aerosol chemistry in atmospheric processes such as acid rain formation and stratospheric ozone depletion. The current ...

Understanding the intricate chemical processes of the atmosphere is key to predicting and improving air quality. Among these ...

But aerosol particles with dark surfaces (like soot) can also absorb visible light and store it as heat in the lower atmosphere. Aerosols also have an indirect effect as condensation nuclei for ...

My group's research focuses on improving our understanding of aerosol formation and growth using a combination of field measurements, laboratory experiments, modeling, and instrument/method ...
