Heating Rate of Light Absorbing Aerosols

Mar 18, 2018 | News

Scientific paper published in Environmental Science & Technology journal presents a novel methodology for experimental quantification of heating rate induced by light absorbing aerosols (LAA) (Black Crabon – BC and Brown Carbon – BrC) into an atmospheric layer.

Multiwavelength aerosol absorption measurements, performed by the Aethalometer, were coupled with spectral measurements of the direct, diffuse and surface reflected radiation to obtain highly time-resolved measurements of heating rate apportioned in the context of LAA species (BC, BrC, dust), sources (fossil fuel, biomass burning), and as a function of cloudiness.

One year of continuous and time-resolved measurements of heating rate were performed in the Po Valley, which allowed experimental determination of its seasonal behavior and daily cycle.

EXPOSURE TO BLACK CARBON DURING CYCLING

Mar 17, 2018 | News

In the 2017 winter-spring period we performed static and mobile measurements of Black Carbon using our Aethalometers at different sites and cycling routes in Celje, Slovenia.
The results show that street intersections along the cycling routes influence the cyclists’ exposure to Black Carbon and should be as few as possible when planning cycling routes in urban areas.
Exposure can be greatly reduced by moving the cycling route away from busy roads, hence we proposed an alternative route and show that traffic planning and management should include all modes of transport.
