Our team from Laboratory of Atmospheric Chemistry (LAC) visiting Hyytiälä Forest Station during #EAC2024 and appreciating all the detailed measurements in a perfectly preserved beautiful boreal forest 🌲

🤞🏼 Cheers to Andre for an insightful plenary about his long experience as a detective of air pollution sources at #EAC2024 in Tampere.

LAC autumn event? 🍂 let’s go cheese making in the Swiss mountains 🏔️

Air pollution knows no city boarders. In our recent paper, we identify the sources of primary and secondary aerosols arriving in Beijing by relying on the finest mass spectrometers deployed in the center of Beijing. Effective mitigation strategies require joint efforts ⬇️
