The PSI Laboratory of Atmospheric Chemistry studies gases and aerosols in the atmosphere, affected by energy systems and impacting air quality, weather, climate change and human health.
Lab News & Scientific Highlights
Machine learning helps refine aerosol measurement characterization
Machine learning, applied to year-long observations from the Zeppelin Observatory on Svalbard, was capable of refining aerosol chemical characterization specifically those measured with state-of-the-art mass spectrometric techniques.
Carico di sostanze inquinanti causato dagli aerei
I ricercatori dell'Istituto Paul Scherrer PSI hanno misurato quali siano gli effetti dei decolli e degli atterraggi all'aeroporto di Zurigo sulla concentrazione di particolato atmosferico ultrafine. Eseguendo queste misurazioni si sono imbattuti anche in composti lubrificanti.
Swiss–Romanian Research & Innovation Partnership Under the Second Swiss Contribution
The Paul Scherrer Institute (PSI), through its Laboratory of Atmospheric Chemistry (LAC), is contributing its scientific expertise to the Research & Innovation thematic area of the Swiss–Romanian Cooperation Programme under the Second Swiss Contribution, financed by the Swiss Agency for Development and Cooperation.
Identificate le cause dello smog di Sarajevo
Legna, carbone e aria di cucina sono le principali fonti del forte smog nella capitale della Bosnia-Erzegovina. Questo è il risultato di un'ampia campagna di misurazione mobile condotta dai ricercatori del PSI.
