Kraków is routinely affected by very high air pollution levels, especially during the winter months. Although a lot of effort has been made to characterize ambient aerosol, there is a lack of online and long-term measurements of non-refractory aerosol. Our measurements at the AGH University of Scien ...

The photovoltaic industry has been steadily growing over the past 30 years. But for solar cells to help eliminate our dependence on fossil fuels, says Emanuel Sachs, they’ll need to provide trillions of watts of power -- and we are “still a thousand fold from where we need to be.” Sachs’ “photovolta ...

Organic aerosol (OA) is a key component to total submicron particulate matter (PM1), and comprehensive knowledge of OA sources across Europe is crucial to mitigate PM1 levels. Europe has a well-established air quality research infrastructure from which yearlong datasets using 21 aerosol chemical spe ...

Carbonaceous aerosols (CA), composed of black carbon (BC) and organic matter (OM), significantly impact the climate. Light absorption properties of CA, particularly of BC and brown carbon (BrC), are crucial due to their contribution to global and regional warming. We present the absorption propertie ...
