Siyao Yue, a postdoctoral researcher at the Paul Scherrer Institute (PSI), is leading a field campaign as part of the ReCLEAN activities in the Lägern Forest, near Baden. The project aims to unravel the complexities of organic nitrogen in the atmosphere, a critical component in understanding air quality and climate change.

Using mass spectrometers, including EESI, VOCUS, and AMS, Yue and his team are meticulously analyzing atmospheric samples. These instruments enable the precise identification and quantification of organic nitrogen compounds.

This research promises to advance our knowledge of atmospheric chemistry, with potential implications for environmental policy and public health. ReCLEAN scientists are striving to unveil the mysteries of organic nitrogen in the atmosphere.
