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 ...

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 ...

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 and clouds play important roles in determining the Earth’s climate. Trace gases and aerosols, constitute only a tiny fraction of the atmospheric mass, however they interfere with ...

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 ...

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 ...

The air over urban sites have much more complex chemical composition than we think. The complexity arises from the presence ...
